Connection problems with SEE urls

[monkeydom]

Short Description

A collaborator and I have been using SEE to meet remotely (weekly) since 2004. Since I upgraded to Catalina, we have weird behavior: I have trouble joining sessions he is hosting.

Steps to Reproduce the Issue

1. I click the SEE url and my window only partially opens; it hangs on "joining session"

2. I can join the session if I open a bug report tab: then suddenly the session is visiable as a tab and we can meet.

3. I can export our session as a webpage but I can't save it ("save" and "save as" etc. are all grey).

Additional case that might also be related:

• join a document using a see url on 10.15
• close the window

Expected Result:

The Hosting party should see that the document was left

Actual Result:

The Hosting party does not see that, and the client can't rejoin easily either.
