There is a persistent error ever since I upgraded to php8.1 and added a new connection to the upstream of the load balancer. I have looked into all the possible errors and cannot see anything wrong with the configurations. This is a Very recent problem and is a big issue as it causes downtime on the site due to 502 bad gateway error…
The error logs on the load balancer site.com-error.logs show this.
[error] 749104#749104: *1042482 no live upstreams while connecting to upstream, client: IP, server: site.com, request: "GET / HTTP/1.1", upstream: "http://proxy_pass/", host: "site.com"
This error started showing up more times and I changed the max fails to be 3. This does not fix all the 502 errors I get in the access logs. it just masks the issue. The fact that I added a new server into the upstream could be the issue but the requests still go through to php and the site stays up until the 502 errors come in. And then I get a “no live connection error”
I would really appreciate any help here! thanks
