Hello! I’ve been using NCP for more than a year. Running version v1.35.0 on a raspberry pi.
Now letsencrypt cert update fails (timeout during connect).
I did not change anything in my setup. ports are accessible and the ddns.net adress is valid and up to date.
Did anyone have the same issue recently and found a solution?
certbot.errors.FailedChallenges: Failed authorization procedure. […].ddns.net (http-01): urn:ietf:params:acme:error:connection :: The server could not connect to the client to verify the domain :: Fetching […]: Timeout during connect (likely firewall problem)
Could be:
DNS services slow,
Interupted or bad internet connection.
Wait for cpl minutes and try again, or run certbot manually using DNS txt record to verify.
Hello,
DNS server is set to Google (8.8.8.8)
Internet connection is flawless for everything else.
I tried the letsencrypt web interface a couple of times over the last days.
run certbot manually using DNS txt record to verify.
Can you point me to the correct instructions for this? Thank you!
I found the cause of the problem: nc-httpsonly i.e. “Force HTTPS”
Apparently checking this option makes a regular certificate renewal impossible? It might be a good idea to point that out somewhere either in nc-httpsonly or letsencrypt
Still an existing bug in v1.46.9. Letsencrypt renewal fails multiple times, turning nc-httpsonly off required to make it work.
