I set up a new API Rate Limit like allways but the saving took for ever
After Reloading the page all rate limit entries are gone / not loading anymore. The page is still responsive. 
I can see the newly created rate limit in the ratelimits.ps1 file.

Hello @Dynamic66
Thank you for reporting this issue and for providing the screenshots.
I understand that when creating a new API Rate Limit in PSU 2026.3.3, the save operation takes an unusually long time. After refreshing the page, the Rate Limits list remains loading, even though the new configuration is present in `ratelimits.ps1`.
To help us narrow down the cause, could you please confirm the following?
1. Does this happen with every new Rate Limit, or only with a specific configuration?
2. Could you share the Method, URL pattern, Limit, and Period used for the affected rule?
3. Do you see any errors in the PSU System Logs around the time you save the rule or reload the page?
4. When the Rate Limits page remains loading, does your browser's Developer Tools (Network tab) show any failed or pending requests? If so, please share the HTTP status code and relevant error message.
We will also look into reproducing this behavior in PSU 2026.3.3 to better understand what may be happening.
