Hi - Hope I picked the right sub-forum for this. Just did a clean install of OMV5 and installed Docker for nzbget using pretty much the same parameters used for the same container in OMV4. Only some paths changed.
I have 3 news servers configured in nzbget and every one of them fails if I use their regular domain names, but succeed if I use their corresponding IP address. This leads me to think it's a DNS issue. But I think DNS is configured properly. I have tried the Cloudfare DNS (18.104.22.168) and google (22.214.171.124). Makes no difference.
root@omv:~# host news.usenetserver.com
news.usenetserver.com is an alias for usa.na.news.geo.usenetserver.com.
usa.na.news.geo.usenetserver.com is an alias for news.iad.usenetserver.com.
news.iad.usenetserver.com has address 126.96.36.199
news.iad.usenetserver.com has address 188.8.131.52
I've put in a ticket to Usenetserver but I'm not expecting a lot of help. It's not really their problem, just verifying configuration with them.
PS: I did find one fairly recent posting about DNS problems but unfortunately I can't read German.
