[I] [Bug][config-ui] server failed to resolve - invalid UDP DNS response [incubator-devlake]
tobiasholzner-whiteduck opened a new issue, #8158:
URL: https://github.com/apache/incubator-devlake/issues/8158
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-devlake/issues?q=is%3Aissue) and found no similar issues.
### What happened
We are running DevLake in an Azure Container Apps Environment. We have seperate Container Apps for Server, UI and the Dashboard. It worked well until the UI started to return 502 bad gateway errors. If I read the Nginx Logs I get the following error:
`
2024/10/23 13:11:30 [error] 18#18: invalid UDP DNS response 22651 fl:85A0
`
`
2024/10/23 13:11:30 [error] 18#18: invalid UDP DNS response 7473 fl:85A0
`
`
2024/10/23 13:11:33 [error] 18#18: *83 app-apache-devlake-prod-server.asdf.westeurope.azurecontainerapps.io could not be resolved (110: Operation timed out), client: 100.100.0.83, server: localhost, request: "GET /api/version HTTP/1.1", host: "app-apache-devlake-prod-ui.asdf.westeurope.azurecontainerapps.io:443"
`
- If I lookup the server with nslookup or by using curl with the nginx user the name gets resolved.
- When I restart the container it works for a few times
- The /etc/resolv.conf show me that I use the nameserver 127.0.0.11
- I use the v1.0.1 with the Images from Dockerhub
### What do you expect to happen
To work well, like before
### How to reproduce
- create seperate ACAs and call /api/version on the UI ACA
### Anything else
_No response_
### Version
v1.0.1
### Are you willing to submit PR?
- [ ] Yes I am willing to submit a PR!

I solved the issue with explicitly disabling ipv6 dns resolving in the nginx config:
`resolver 127.0.0.11 valid=300s ipv6=off;`
It seems that this is necessary for k8s and aca
