Were you able to access the tool at all? Did you get prompted to login before receiving this error message?
Same error here, it allowed me to log in at 1946 GMT, but when it went to the next page (https://rtqm.beta.qrz.com/qsomap) a 500 error came back.
An issue has been identified where users that have not previously used RTQM before receive a server error when logging into RTQM for the first time. This has been traced to an issue with initialization of filters and should be corrected in version 2025.09.002
Version 2025.09.002 has been pushed to the Beta Test server and should correct this issue. If you've experienced this issue, please try again.
