403 Forbidden: Unknown session about teleconsole

[kontsevoy]

I think I figured this out. Teleconsole uses Teleport SSH certificates under the hood and if the client/server time do not agree you may get an expired certificate. We're releasing Teleport 3.0 soon and I will be updating Teleconsole on it which should make a lot of things smoother. Going to keep this open for now.

I meet the same issue with v0.3.1 , debug log is as below.

There is https_proxy, and curl https://teleconsole.com, curl https://as.teleconsole.com, and so on, are no problem.

Don't know why it said "unknown session". I guess "session" is about SSH, but "403" is HTTP status code.

In addition, it fails to join session, either.

hey guys, I have been trying to reproduce this, to no avail... the proxy is running on Azure and is periodically taken down for maintenance (brief downtime) so if you try to start a session in the middle of a daemon restart, you'll see this.

Kind of strange bug. The problem with connection disappears when I change my system time to UTC.

@kontsevoy I am experiencing a problem when teleconsole disconnects the user after a few minutes. Is it somehow related to this? What is the solution?

[kontsevoy]

@Kampii teleconsole is a free service and lately there's been a big growth in usage. Short answer: your nearest POP (there are 3) gets overloaded eventually. We'll see if we can allocate more resources to it soon.
