socializer signalr server returned handshake error handshake was canceled

We are using the socializer docker container hosted on Centos 7.3 OS in our greyspace, and using the GHOSTS browser handler to browse to the page, do posts, click on links, etc with Firefox. We have socializer mapped to www.tweeter.com.

We are getting consistent javascript errors written to the console, I guess thrown by the Geckodriver, that is:
www.tweeter.com/js/signalr.min.js, line 16: Error: Server returned handshake error: Handshake was canceled.

I have googled around for this error, and it seems it may have something to do with websockets on the server not being enabled, but I don't know. Have you seen this error? Other than polluting the console window output, it does not seem to be affecting operation.

Hmm, have not seen it, but haven't been looking for it either - give me a bit to do some investigation. Thanks for reporting.

More info, seems to only occur on Firefox, using v125. Does not occur on Chrome. It is not a big deal, does not seem to affect operation.
