JetBrains Toolbox untrusted certificate popup


I just got this untrusted certificate popup when opening JetBrains Toolbox v. 1.18.7455.
I selected Reject, and the application seems to run normally.

Is this an error?

I would guess you are using AT&T thats a typical error from their gateway when it is failing to connect… Nothing to do with jetbrains.

AT&T is my ISP, but why would that show up in the JetBrains Toolbox window when launching that application, and not show up for any other application?

Because at that point in time the IDE did a request to an HTTPS endpoint and your gateway decided to return its own thing with its self-signed certificate… If the problem was just transient, that may have been the only request that happened during that period or the other applications didn’t complain about the certificate…
