Maybe others are affected as well, so I’ll post it in here as well: I use this app with Signal. This morning i received messages, but now i don’t receive messages. If iI try to send a message i get an error message:
Apikey Correct. ▶️ 👍 Message not sent!Error code: CAPTCHA required. Please inform signal@callmebot.com to check what happens.
I’ll reach out to callmebot according to the error message.
Edit: Sending an email is harder than I expected. Assuming signal@callmebot.com and support@callmebot.com are valid e-mail addresses, they are refusing my mails. I’ve tried first with an SimpleLogin email alias and second with a new emailaddres on a custom domain. All four emails cannot be sent
