[Bug or setup issue] Indefinite wait when running cdp commands

[Soggy-Pancake]

I am trying to connect to a chrome instance running within a docker container from the host. It seems to have successfully connected but it indefinitely waits for a response and does nothing after calling tab.query_selector() or browser.get(). This happens with both nodriver and zendriver.

Logs:

Docker container running chrome is zenika/alpine-chrome with the arguments --no-sandbox --no-first-run --remote-debugging-address=0.0.0.0 --remote-allow-origins=* --remote-debugging-port=9315 about:blank

I can reach the devtools /json/version with no issues.

Here is an example of where it is getting stuck.

print("getting login button")
button = await page.query_selector("#thebutton")
print("The button:", button) # never gets printed

The container may have been the issue. I got a response back once and then got this

[0202/041123.029509:ERROR:cmd_buffer_helper.cc(141)] ContextResult::kFatalFailure: CommandBufferHelper::AllocateRingBuffer() failed

Switching to nextools/chromium seems to have fixed the problem! Leaving this up as no timeout is still a problem.
