[...]Well, that is working, somehow, except: If the LE server addresses Host A, the challenge file is going to be retrieved instantaneously. If the LE server addresses Host B, only every *other* request is being served instantaneously: 1. access: immediately download 2. access: 60 s wait, then download 3. access: immediately download 4. access: 60 s wait, then download etc. Hmm, default proxy_connect_timeout is 60s, I know. But why every other connect?You are using "proxy_pass http://local-at-host-A.lan;"; in your configuration. What are the IP addresses it resolves to? The behaviour observed suggests that the name resolves to 2 different addresses, so nginx uses round-robin to balance between these addresses, and only one of these addresses is reacheable.
Bingo! I had had two issues in that regard: My local resolver returned one IPv4 and on IPv6 address for local-at-host-A.lan, and in my server block I had had an include statement with listen statements for IPv4 and IPv6 addresses. (Those were left-overs I didn't bear in mind when removing IPv6 functionality for that given nginx server.)
Now, everything is working as expected. Thank you very much for pointing me to the right direction!
