I looked at our Web Conferencing Edge and noticed two errors (neither of which you will find any information online about them… I guess I am the lucky one): It’s a Web Conferencing Edge problem, not something with the client to the Reverse Proxy. What I noticed is, I got the same exact errors even when trying to utilize polling or whiteboarding. I tried the other Web Conferencing functionality on the client. This verified the client was really not even getting to the point of trying to communicate with the Reverse Proxy, especially since the Network Monitor logs didn’t even see the request try to go out.Īt this point, I was at a bit of a loss and went back to basic troubleshooting more and sometimes, we often overlook the basics. When I started the Query, I saw absolutely no traffic for Web Conferencing PowerPoint Presentations at all. Once ready to start logging, choose the Start Query Option.
You can easily obtain your Public IP on your client machine by going to Once done, choose Update. Once at the bottom of the dialog, choose Filter By IP and set the Value to your Public IP Address. I went to the Logs & Reports and modified the filter I wanted to see anything that came into it with my Client IP Address. So I went onto our Reverse Proxy Server which is Microsoft Forefront Threat Management Gateway (TMG). But when I tried uploading a PowerPoint Presentation in an Online Meeting, I never saw a call go out to the Reverse Proxy. Because of this, I knew the Reverse Proxy was functioning just fine, especially since I could also access our Simple URLs ( and from the outside). What I saw is, when I would add a new distribution list to my contact list which is a function of the reverse proxy, I properly saw in the trace the client make a request out to the public IP of our Reverse Proxy Server.
The first thing was that I loaded up Network Monitor on my client. I did two things to troubleshoot whether it was the client hitting the reverse proxy and having it not function correctly.

SHARE SCREEN LYNC WEB APP FOR MAC
So I guess I can't use Lync for Mac on macOS Catalina. Contact the developer for more information. The developer of this app needs to update it to work with this version of macOS. I tried the second option of using Lync for Mac, but when I try to run Lync I get this error: Could the plugin be incompatible with 64-bit macOS Catalina? If I try to join at this point I end up in a "Virtual Lobby" but I'm never able to advance from that point, presumably because the plugin is not working. Plug-in installation is taking longer than usual.

When I go back to the same page after installing the plugin, I am either prompted to install the plugin again, or I get this error message: I don't know which browser this is for, but I assume it should work in Safari. After installation I see a new plug-in in ~/Library/Internet\ Plug-Ins called SkypeForBusinessPlugin-15.8.bundle, so the installation is apparently successful. I can run this and choose to "Install for me only". If I enter my name and click "Join the meeting" my browser downloads SkypeForBusinessPlugin.pkg (md5sum = a4958d5aa5c7dbe17774bcd6e4492106). Here's a screenshot of the screen I start with. But every time I try, it seems to send me in loops with the same prompts to install the plugin again and again. Using my Mac I'm trying to join a conference call hosted using Skype for Business Server.
