Gitlab Helm Upgrades

I am having an issue upgrading gitlab from helm chart 4.2.2 to anything higher. The upgrade succeeds however i then get “Internal API unreachable” errors when making changes to projects.

Here is the error i see in the gitaly pod logs:
{“duration_ms”:3007,“error”:“Post http://gitlab-webservice:8181//api/v4/internal/allowed: dial tcp connect: no route to host”,“level”:“error”,“method”:“POST”,“msg”:“Internal API unreachable”,“time”:“2020-08-16T19:33:50.539Z”,“url”:“http://gitlab-webservice:8181//api/v4/internal/allowed”}

Has anyone come across this?
