Lots of users having to clear browser cache

[mgranillo]

On QSEoW we are getting a lot of reports of users unable to access Qlik. An error message does not pop up, the hub simply does not populate with content. Clearing their browser cache seems to resolve the issue. Does anyone know why this would start occurring?

Hello ,

1. Did this issue start after an upgrade?
2. Are you using SAML?
3. Please perform a HAR file trace for an affected user and look for the 431 error.
4. If you see the 431 error , review the remaining two article below (2 and 3)

Yes, it started after an upgrade to May 2024. We also had windows patching the same day.  

Yes, we use SAML

Thank you for the suggestions. I will attempt a HAR file trace the next time this comes up.

@Ray_Strother I was able to confirm some of our problems are due to error 431. Before making changes to our environment as outlined in the articles, I want to ask why I wouldn't see the issue across browsers. One of our users typically uses Edge and was unable to access Qlik, but the same user was able to access Qlik without an issue in Chrome. Is this indicative of another problem?
