Problem solved. Thx to Athom support.
I don’t know why, but as my explanation for this problem - that they’re testing IPV6 on device firmware.
Answer on my ticket:
“This issue seems to be caused by your internet modem issuing IPv6 addresses. Could you please disable IPv6 in your internet router? Please also send us a screenshot from https://test-ipv6.com/ If possible, could you reboot your internet modem once? Then please reboot your Homey Pro once, try to install an app and then send a diagnostic report to us?
I look forward hearing from you.
Best regards, Arno”
I go to my Mikrotik, shutdown IPV6 tunnel, turned off IPV6 setting and also forwarding and after send to reboot Homey. Two minutes later all Apps installed by themselves successfully.
