@kkaraivanov1 Thanks for looking at the PR. I agree that group data should be refreshed as well. Is group membership info already being stored on authentication?

That makes sense, and thank you for the clarification. Adding support for `user_info['groups']` is probably best addressed in a separate PR. I'll be happy to revise this PR to follow...

This looks similar my PR #475 with an attempt to add OAuth token refresh to generic. In the momentum to implement refresh, please consider it as well.

These are the changes I'd made to add a `--nanny-port` argument to the worker. https://github.com/jthiltges/distributed/compare/main...jthiltges:nannyport

I'm getting the impression that submit50.mit.edu storage isn't part of the CMS XRootD data federation. Looking at the MIT redirector, I'm not getting a result: ``` $ xrdfs xrootd.cmsaf.mit.edu ls...

Hi Oksana, can you confirm that the plugin is being built of the xcache branch? Some of the strings suggest it's coming from master. At least for `hub.opensciencegrid.org/coffea-casa/cc-ubuntu:2023.03.17`.

Interesting result. This appears to partially be an issue with our xcache (running in docker). The xcache tells the client to contact 172.23.0.2, which is a private IP of the...

I was able to bisect this behavior change to 53f7050c6c903d8a7c1999f3b923c2f38ac449ff. Mirror support appears to be an outstanding feature request: https://github.com/google/go-containerregistry/issues/1200

I think substituting the hostname would definitely be a possible path. Where I'm hazy is how to neatly represent the configuration. The [containers-registries.conf](https://github.com/containers/image/blob/main/docs/containers-registries.conf.5.md) syntax allows fairly granular configs, down to...

My understanding is that each [mirror instance](https://docs.docker.com/docker-hub/image-library/mirror/#run-a-registry-as-a-pull-through-cache) can only serve a single registry: one `proxy.remoteurl`. Handling the docker.io registry alone would address our site issues. But my preference would be...
