The WebSocket is in an invalid state (`Aborted`) for this operation. Valid states are: `Open`, `CloseReceived` #930

Open litiansum opened 5 years ago

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?

eddex commented 1 year ago

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

olivermonberg commented 1 year ago

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.

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?

raman-m commented 8 months ago

@tsoen Do you have an intention to contribute to resolve this problem?

@raman-m @AlyHKafoury Is there any chance we got it fixed before 5 years pass since reporting (Jun 15, 2019)?

@zamojski Adam, Yes it is, if you are going to contribute... Are you? Aly has not responded to my messages for more than 2 months. He has been unassigned.

hogwartsdeveloper commented 1 month ago

I would like to do it.

raman-m commented 1 month ago

@hogwartsdeveloper You are assigned! But keep in mind, it's better to deliver your current open PRs first! So it's strongly recommended to work on 1-2 PRs concurrently, no more!
