Ocelot The WebSocket is in an invalid state (`Aborted`) for this operation. Valid states are: `Open`, `CloseReceived`

When connecting SignalR through Ocelot, after refreshing the webpage, an exception will be prompted, but the normal function will not be affected.

Still seeing the same error msg, any update on how to solve?

May 11 '22 04:05 b7luestar

Still getting this error. WebSockets work as expected but the error appears very often in our logs which heavily clutters our log files.

We open a WS connection from a website. The exception is logged every time the website with an open WebSocket connection is reloaded.

Same issue here when a microservice with WebSocket shutdown gateway and other microservices shutdown after

Feb 23 '23 09:02 MrSEKIRO

Same issue here, I can confirm that it happens when a website with an open WebSocket connection is reloaded or when the website is closed.

@eddex Marco @MrSEKIRO Abolfazl @olivermonberg Oliver Thank you for being active this year, and pointing to the issue multiple times!

I'm going to prioritize the issue...

Hello @raman-m We are using the 18.0.0 version and encountering this issue, I just wanted to check if it had been resolved in newer versions (as this issue is still marked as Opened but linked PR are Closed).

Regards

@tsoen commented on Nov 14

Hi Timothee! Unfortunately the issue is still active. We have no developers enough, also contributors didn't provide good PR with a fix. I am busy as usual with other issues... Old PR #1576 was closed by the author. So, the author doesn't want to develop more to deliver the fix finally. Could you clone feature branch from #1576 and make some tests please to confirm that the bug fix is good?

Nov 14 '23 11:11 raman-m

@tsoen We will try to fix this bug in this month, and deliver a fix by including it in November'23 release... Do you have an intention to contribute to resolve this problem?

Nov 14 '23 11:11 raman-m

@AlyHKafoury what about this bug to work on? I'm proposing it because of high priority. Not hard for you?!.. 😉

Jan 19 '24 14:01 raman-m

@raman-m I got it assign to me.

Jan 19 '24 14:01 AlyHKafoury

@AlyHKafoury You're assigned. We'll do some pair programming. Keep in mind, this issue has a lot of bottlenecks. With possible multiple scenarios and technical & technologies combinations. So, it's not marked with "large effort"" label. But it is with medium effort. So, we have strong medium effort here, because of wide and complex testing, and multiple user scenarios of technologies vs tools vs browsers. But, yes, possible fix in C# can be even tiny, in a couple of lines. Finally, I'm not sure on complexity...

Jan 19 '24 14:01 raman-m

@AlyHKafoury Do you work on this?

Mar 05 '24 09:03 raman-m

Hello Raman,

Yes I have written some unit tests for this, still needs more work

Best Regards, Aly Kafoury

@AlyHKafoury Unit tests are not sufficient to deliver the feature! Or did you mean unit tests to reproduce the bug? Did you fix it? Do you have a possible solution for that?

I'm worrying you worked for 1-2 months, but I don't see the progress here. This is not easy bug... Seems team work is required. first, we have to brainstorm this bug...
