No, not in the same network.
And I check the log again, seems everytime when 502 issue happens, there is something like next:
{"log":"[Tue Sep 15 02:14:58.023302 2020] [proxy:error] [pid 332:tid 139822047946496] (32)Broken pipe: [client 10.192.244.203:54182] AH01084: pass request body failed to 127.0.0.1:8000 (127.0.0.1)\n","stream":"stdout","time":"2020-09-15T02:14:58.319479074Z"}
{"log":"[Tue Sep 15 02:14:58.023352 2020] [proxy_http:error] [pid 332:tid 139822047946496] [client 10.192.244.203:54182] AH01097: pass request body failed to 127.0.0.1:8000 (127.0.0.1) from 10.192.244.203 ()\n","stream":"stdout","time":"2020-09-15T02:14:58.319481826Z"}
What is 127.0.0.1:8000? Reverse proxy in lava setup? Any suggestion?

Are you in the same network as the server?

Yes, Remi, we tried it like next:
staging:
token: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
uri: http://lava-staging.sw.nxp.com/RPC2
username: larry.shen
timeout: 300.0
The only result is the error message becomes:
Unable to connect: HTTPConnectionPool(host='lava-master.sw.nxp.com', port=80): Read timed out. (read timeout=300.0)
And another guys which directly use XMLRPC to submit without set timeout, will directly get 502, I think the root cause is same. The server is handling connections which cannot response client, the lavacli timeout even 300 seconds.

Have you tried increasing the lavacli default timeout. Maybe the network connection to the server is flaky?

I just checked the log, looks there is nothing in server log.
Just, we use container master, and get next from docker logs, these happened when user sometimes submit job failure, will it possible be the cause? What does it mean?

Looks really weird. We're also running eventlet gunicorn and it actually improved things a lot (no more weird timeouts). Maybe Remi has some better idea.
