Problem with ChirpStack V4 Web-UI - gRPC Error

Hi everyone!
In the Web-UI section, when viewing the details of Gateways or the details of Devices, an error occurs and you are logged out.
It should be noted that the server has been working without problems for about 2 months and this problem occurred today.
So far I have noticed the following errors:
1- in web browser:


2
3

2- in postgresql log file

Thank you for your advice

@brocaar
can you please check this and suggest a solution

And this is the ChirpStack log:

I found the problem.
The problem is due to changing the summer and winter time of the server. But is there a way that the error does not occur?
@brocaar

A panic is an unrecoverable exception, or at least how I interpret it. So it crashed, due to the timezone changing.
Perhaps the server does not handle changes to the timezone well, without a restart? Have you tried restarting Chirpstack after updating the timezone?
