Hi Walter, what save button? maybe here some pictures: No access through the eve app: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/6/4693d67e01290aab4f7ad9b5224624d413c90b25.jpeg) MyEve can find it, but not connect: ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/a/3ab361e2c669e0134bf8bdd9af3311b26b8753fb.png) ---

You have to make an account for loging in to the ace server installer app like wil\_ree mentioned. After that you will probably be able to reset the in-operative to operative drop down box like shown in previous screen dumps ---

I have an account made on [https://aceservice.alfen.com/](https://aceservice.alfen.com/) But this account login does not work on the ACE app (the one I use from the internet does work to log in).

nope, did a full check with claude, can ping the unit, all works, but cant reach it. the webserver at port 80 has hung… reboot doesn’t solve it. need Alfen to solve this ---

Hi Patrick. It’s not that difficult, but you need two things. An account with Alfen AND a username and password for the software tool Option 1: The official route (for installers) # **How do I receive login details for the ACE Service Installer configuration tool?** _This articles explains how to request credentials for the ALFEN ACE Service Installer._ **PasswordACEInstallerConfigurationLoginAccount** Share This articles explains how to request credentials for the ALFEN ACE Service Installer software. An account for the ACE Service Installer configuration tool can be requested via our support portal. You can create an account by following the steps below. **Step 1: Go to our support portal and log in.** Visit [support.alfen.com](https://support.alfen.com/) **Don’t have an account yet?** Create one now to continue by clicking the ‘Register’ tab. ![image-20241114-071745.png](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/0/3/030b1cea549fb826ad1890bc6161e0aca9cd159c.png) **Fill in the form to request the account** ![image-20241114-071937.png](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/7/1794632f4e24bb70210d2bebd5ab98032ebc7116.png) **Step 2: When logged in** you will see a similar screen, click ‘Go to Charging Equipment Support Portal’: ![](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/f/afe6b1d09103c751de08c2013976d8e47c61f4c4.png) **Step 3: Click on “Manage your services”.** ![image-20241114-072037.png](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/4/e48a7ee3f18fb54ff819df019885142fa0d4087a.png) **Step 4: Select 'Request for Sign-up"** ![](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/3/a3b652188cdd1ae666e52e54e216af8023d0eb8e.png) **Step 5: Fill in the form and click on “Submit”.** ![](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/a/1a22fb9e6c4f153fcedd938fda65fc1f83c8aa7b.png) Shortly after submitting the form you will receive your ACE Service Installer login credentials by mail. If you haven’t received the email within 15 minutes, check your spam box. **SO THESE ARE DIFFERENT USER AND PASSWD THAN THOSE OF YOUR ALFEN ACCOUNT. (ONLY FOR THE SOFTWARE TOOL)** (that is wat i did, and you have your own account, so you can also save settings) OPTION 2 Or you go to [Handleiding: Plugfuse op Alfen - Plugfuse Charge Point Manager](https://plug-fuse.com/service/handleiding-plugfuse-alfen/) and follow the steps. But this is not a own account, so Opion one is better I think ---

thanks, that was already successful, but thanks for taking the time to extensively write it out! hopefully will benifit others as well. Ticket was made with Alfen after I investigated with Claude, where we concluded there is an issue with the websocket, port 80 is not reacting anymore. port 443 is fine, open and responsive. conclusion is non of the webapp related activities works for now. Alfen directed me back to the installer (50five), and they have this great AI enabled service desk, that just makes a ticket for you and you have to wait till an actual person has the time to call back. Never have a unit installed by them. service is non existent… Still waiting after 5 days, without the ability to switch the charging mode of my alfen… there goes all my PV based electricity ---

You probably already tried it, but have you turned off your Alfen charger completely for a minute and then tried turning it back on? For me it does miracles when it doesn’t respond anymore. ---

Update on my issue. I’ve crimped both connectors on the cable again as I was a bit suspicious of those. First going to try to see if Eve is more stable now and then I’ll switch to the app again. For now it still works, but it’s only been a few hours so far. Let’s see tomorrow morning… ---

Thanks for the tip, and yes tried that as well. Did the following Symptom: ACE Installer and myEVE app both report the device as unreachable/communication error, despite it appearing in discovery. Password is correct but login never gets far enough to be validated. Checks performed, in order: ICMP ping to 192.168.0.xxx — succeeded, 4/4 packets, TTL 255, avg 23ms (one outlier at 83ms, rest 3ms). Confirms basic L3 connectivity and that the device’s network stack is alive. ARP table — 192.168.0.xxx resolved to a valid MAC , locally-administered bit set, unlike the registered Alfen OUI seen on 192.168.0.xxx). Noted as a minor anomaly but not pursued further since discovery resolved this IP from the charger’s own broadcast. TCP port 80 — closed (TcpTestSucceeded: False). Expected if the service interface is HTTPS-only. TCP port 443 — open (TcpTestSucceeded: True), both before and after the reboot below. myEVE app from a phone on the same network — failed with “charging station webserver communication error,” ruling out a PC/ACE-specific cause and confirming the fault is on the charger itself. Full power-cycle of the charger (breaker off 30s, back on, waited for boot) — port 443 remained open afterward, but ACE/myEVE still fail the same way. Rules out a simple hung-process state that a reboot would normally clear. PowerShell HttpClient HTTPS GET to [https://192.168.0.xxx/](https://192.168.0.xxx/) with cert validation disabled — no response and no exception after waiting, indicating the TCP handshake completes but the TLS handshake never completes/hangs. Conclusion: TCP/network layer is fully healthy (ping, ARP, port 443 open) both before and after a full reboot. The fault is isolated to the charger’s TLS/web-service layer — the socket accepts connections but the TLS handshake never finishes, which is why every client (ACE, myEVE) reports a generic communication/reachability error rather than a credential error ---

With my charger, when the server on 443 locks up, I need to **physically** connect the charger UTP to my laptop (set to dynamic address). Check ipconfig to see you’re getting an IP and then connect the charger to your local network again. You literally don’t have to do anything in between, the change in IP seems to trigger things. After doing so, the webserver will have restarted and accepts connections from the Eve Connect app again. Power cycling the charger does NOT fix this for me; Eve Connect or ACE won’t connect. The physical reconnect is the only thing which works, weirdly enough. I’ve got this charger for over 5 years now and the hardware never failed me once. But software wise, Alfen seems to have made some weird design decisions I don’t really understand. ---

Open the charger (6 x torx screw) and I the left upper corner you find the utp And P1 connector (for load balancing). If it is now not connected, how do jou normally connect to your home network? WiFi? Mine has no WiFi. Is it a extra option?
