M_UNKNOWN for a room that exists

[andybalaam]

Steps to reproduce

1. Within develop.element.io, looking at the room listedn in the error message below.
2. Saw an update was available and clicked Update Now

Outcome

What did you expect?

To return to the room I was looking at.

What happened instead?

I received this message:

#element-web-internal:matrix.org is not accessible at this time.

Try again later, or ask a room or space admin to check if you have access.

M_UNKNOWN was returned while trying to access the room or space. If you think you're seeing this message in error, please [submit a bug report](https://github.com/vector-im/element-web/issues/new/choose).

Soon afterwards I received Connectivity to the server has been lost. banner (at the same time as this comment)

When I refresh the page I get the same error, but when I switch to the room with Ctrl-K, it appears.

Same problem on app.element.io

Getting this in console:

Getting filter failed M_UNKNOWN: MatrixError: [429] Server is unavailable (https://matrix-client.matrix.org/_matrix/client/r0/user/%40andybalaam%3Amatrix.org/filter)

[andybalaam]

So I'm being rate-limited.

I'm not sure what is RVS

I saw an issue that was causing lots of requests, but I can't find it. If this is an example of that issue, I remember that it was actually fixed, but any users hit by it need to wait for the queue of requests to drain and then it will start working again.

If/when I find the issue number I'll double-check this and then mark this as a duplicate if that seems right.

Meanwhile, matrix.org might be struggling a bit, maybe because of this problem.

[andybalaam]

It seems to be healthier for me now. @argentatus-larus ?

sorry, this was a partial outage on matrix.org, between 10:30 and 11:10 or so, UTC.

[larus-argentatus-sec]

Same, all good, thank you!

you may be thinking of #24167? I don't think that's related here.

[weeman1337]

you may be thinking of #24167?

At least for me, it didn't trigger a rate limiting on m.org. Do the rate limit checks depend on the endpoints?

Yes, but I don't think #24167 is related here, and nor are per-user rate limits.

Yes I was, thank you.

[andybalaam]

OK, so this was down to a partial outage on matrix.org, closing.
