Hello,
This quick post just to let you know of my latest trouble : I had a fully operationnal Ynh install, and then one day my LetsEncrypt certs refused to be renewed.
When I did it manually, the log displayed an error “Challenge failed” but the 3 lines of IP debugging (provided by ynh tool) were identical :
- 2020-05-12 15:20:26,549: WARNING - Debug information:
- - domain ip from DNS 163.172.XX.54
- - domain ip from local DNS 163.172.XX.54
- - public ip of the server 163.172.XX.54
BUT in the json-line just above, I could read that it used an IPv6 adress u'addressUsed': u'2001:bc8:YY:1302::1' .
My VPS had changed of IPv6 adress, but was still at the same IPv4. Thus I could connect via web (as long as certificates were not expired) but the LE challenge failed.
As soon as I updated my AAAA field, at my registrar’s DNS, the challenge went succesfully.
Maybe the debug info could include IPv6 ?
Anyway, thanks for the good work, and may the sysadmin-force be with you !
