I can tracert through all hosts. Perhaps it was down for maintenance? Can you open in your browser?

I have 2 servers but 1 can not reach apps.nextcloud.com

2 server with different public IP prefix (/24)
server 1 YY.155.197.XX
server2 YY.155.196.XX

Just 1 of my servers can’t reach.
Another server can ping and traceroute.

DNS answers are sometimes cached by a device. USe nslookup Use e.g. "nslookup " to check the resolved ip address and make sure that you clear any DNS cache and try again.

DSN answer correct IP (176.9.217.53)

But traceroute stuck at s2.nextcloud.com

traceroute to apps.nextcloud.com (176.9.217.53), 30 hops max, 60 byte packets

It might have been a temporary problem. I’ve just tested it and I was able to access the server without any problem:

BTW, your general latency seems to be extremely high (>200ms)?!
