Thank you for opening a bug report. Unfortunately, the information you have provided is not sufficient for someone else to attempt to reproduce the reported behavior. Remember, each bug report must include detailed steps that someone else can follow on a clean, empty NetBox installation to reproduce the exact problem you're experiencing. These instructions should include the creation of any involved objects, any configuration changes, and complete accounting of the actions being taken. Also be sure that your report does not reference data on the public NetBox demo, as that is subject to change at any time by an outside party and cannot be relied upon for bug reports.

Adding to this, @BH-NetAdmin please try to use a timezone from https://en.wikipedia.org/wiki/List_of_tz_database_time_zones.

It sounds like you've entered "EDT", which would be invalid. NetBox will not boot, and then the 502 will be returned from the reverse proxy because NetBox isn't running.

As @stuntguy3000 points out, the list of valid timezones is referenced in the documentation for the config parameter. "EDT" is not a valid timezone.
