playwright timeout error

Start with vwa/src/envs/browser.py at asetup and page.goto, then inspect the timeout wrapper in vwa/src/envs/utils.py. Reproduce the intermittent navigation failure against http://localhost:9980/ while checking the classifieds Docker logs; done means identifying the cause and establishing a reliable resolution.

This error is essentially impossible to reproduce reliably, yet it happens very frequently. Sometimes it goes away on its own after a while, and other times it doesn’t recover by itself. I’ve looked at the classifieds Docker logs but can’t see anything wrong. I’m asking for help—has anyone else encountered the same issue?
