MCP Authentication buttons are not functional

Type: Bug

I have Atlassian MCP installed and I use Agents Window. I was authenticated there but haven't used it for some time. Now when I start it, it says that authentication required, but it doesn't open browser auth automatically, the Sign In button in the settings doesn't work and doesn't open auth as well, in the chat authentication link also doesn't work. I am not able to re-sign-in.
