Google SSO Timeout on Pritunl – Stuck on “Continue” Page and Returns 500 Error

raghav · August 8, 2025, 9:33am

Hi,

We are facing an issue with Google SSO authentication in Pritunl.
When a user tries to log in via Google, the process gets stuck on the Google “Continue” page for a while, and then Pritunl returns a 500 Internal Server Error.

From the logs, it appears the failure happens when Pritunl calls the Google Admin SDK to fetch user or group details. The request hangs for some time and then fails with a socket.timeout during the HTTPS request.

This happens consistently and seems to be caused by network communication issues between the Pritunl server and Google APIs. The errors occur during both service.users().get() and service.groups().list() calls.

What we noticed:

The request stalls before eventually timing out.
The problem repeats for both user and group verification steps.
This ultimately causes /sso/callback to return a 500 error.

We will paste the relevant log snippets below for reference.

and after these 503 errors we started to get these timeouts and the first one was at:

[2025-08-07 21:17:38,340][ERROR] Exception on /key/callback [GET]

But it seems that yesterday it was not that bad, but in the last 1 hour, it happened twice and our team was not able to use pritunl for 10-20 minutes each time.

We use v1.32.4181.41 version.

There appears to be a network outage in the South Asia region affecting connectivity to the Google Workspace API. This is similar to an outage that occurred a few weeks ago in South Asia that impacted connectivity to the Pritunl subscription servers. These are regional issues with internet infrastructure in the South Asia region. I don’t have any further information on this, these appear to be related to government internet shutdowns occurring in the region that cause routing instability.

Hi Zach,

Could you please tell from where did you checked the status of Google Workspace API.

is it from this source: Google Workspace Status Dashboard

zach · August 8, 2025, 12:30pm

I’m getting the information from email reports. It’s only the South Asia region and only Google Workspace API errors.

zach · August 8, 2025, 10:05pm

If the issue is intermittent run the command below. This will disable the hourly single sign-on check for connected users.

sudo pritunl set app.sso_connection_check false

Even issue affects in India

zach · August 9, 2025, 6:01am

This is possibly an issue with rate limiting although I’ve observed it even with 1 request every 10 seconds. There will be a server update in 6-12 hours that will remove the use of the Google Workspace API for the hourly connection checks and use only OAuth for that validation. This update will also limit the requests to 1 request every 2 seconds.

An update has been released Pritunl v1.32.4349.59 that will implement rate limiting and remove redundant usage of the Google Workspace API. This should fix issues with active connections dropping but new connection requests need the API validation. If the API issues continue it may take multiple connection attempts for a user to connect. If set commands were used to disable single sign-on checks temporarily, run the commands below after updating to revert the single sign-on skip options to the default values. These commands can be run even if no changes were made to verify the values have the correct default configuration.

sudo pritunl unset app.sso_connection_check
sudo pritunl unset user.skip_remote_sso_check
