Putting Pyroscope behind nginx ingress causes 500 errors for tags

#### Describe the bug
When you put Pyroscope behind nginx ingress you get 500 errors due to tags not loading. If you refresh or hit execute it usually fixes it. But it's still a problem sometimes And i did set the -api.base-url

#### To Reproduce
Steps to reproduce the behavior:

Put nginx ingress in front of Pyroscope

#### Environment

Kubernetes. Latest pyroscope

#### Additional Context

It'd be nice if there was documentation for configurating nginx ingress to avoid this issue.
