Tried on multiple computers, it is hanging on connecting.
I'm running into the same issue. When I launch it from a terminal (I'm running Linux Mint 18.1) I get this:

EDIT: I forgot to mention, this just started happening for me as well. The messages in my terminal screenshot just keep scrolling by, looks like it's trying to do something with plus.google.com. Did Google just block something that prevents this from working?
I see this happening as well, getting the HTTP 403 errors. I'm surprised it's using plus.google.com domain name. Google Plus is relaunching as Currents soon
We鈥檙e writing to let you know that Currents will become generally available (GA) on July 6, 2020.
I can see right at the start for a new session (deleting my old credentials)

Same issue on macOS 10.14.6, 10.15.5, and Windows 10.
Observing it on Ubuntu 18.04.4. Haven't tested it on Windows 10. I use Linux primarily.
I thank zackotronic for creating a PR. I was nearly pulling my hairs out since I thought it was internet connectivity issue at my end!
Someone know how put Yakyak in debug/verbose mode ?

I think the api key of yakyak to connect in a service is expired
Same issue on MacOS beta 10.15.5 (19F94a)
Same on MacOS 10.15.4. Tried version 1.5.7-beta and 1.5.4.
Same issue on Ubuntu 18.04 yakyak 1.5.6
Same issue on Windows and deleting the profile doesn't help for that.
I'll add my "me too" on MacOS
Same problem on Win10, MacOS 10.15.5 and Ubutnu Linux.
can we please assume its broken for everybody, and stop adding "me toos" now?
Looks like a server-side change broke it. I've created a pull request here: https://github.com/yakyak/hangupsjs/pull/117 Hopefully that can be pulled in soon so we can get a new release with it fixed.
If you want to test the fix, download this file and put it in app/node_modules/hangupsjs/lib/init.js : https://gist.github.com/dcd568967c68c9c203efd99545403b35
@HomerSp - Do not evne have that file(given you didn't give full path, assume u mean resources/app/etc) - can't find lib folder.
found resourcesappnode_moduleshangupsjslib and resourcesappnode_moduleslodashfp (worked when replacing first example)
Be sure that when this fix gets into place that it's reflected in https://github.com/snapcrafters/yakyak too.

It's works ;)
Much obliged, @HomerSp
That did the trick for me on Arch
Should be fixed in v1.5.7 thanks to @HomerSp
With version 1.5.8 problem doesn't exist anymore. I cannot confirm if the same is with fixed 1.5.7 but the newest version works like a charm. Thank you, good job team.
1.5.10 on Windows 7 - Problem is back

When I clear the profile the login window shows up but after providing the credentials it's getting stuck.
no such problems here with 1.5.10 on MacOS Catalina.

Try killing the task yakyak using task manager. Have observed the issue on Linux as well. Few days ago, there was 2 instances of yakyak running but it was still showing Connecting..... Killing the process and starting yakyak opened up instantly.
