Why is the database connection not working on Windows?

Question

Java

Good afternoon, please help me understand why this happens.
I have a Spring project with two databases. The first is Postgress, the second is ClickHouse.
All this is developed under openjdk.
Initially, the development was carried out on a Linux machine, working with the ClickHouse database worked.
After, for a number of reasons, I had to transfer development to a Windows 10 machine.
At the same time, the connection to the database stopped working, when you try to make a request, it drops out in trace

If you compile the project into a Jar and put it on a Linux machine, all queries with the database work.
If this Jar is transferred to a Win machine, then we get a 500 error.
What can be wrong ?
UPD. I was able to fix it, but to be honest, in a crutch way. Switched to the official Http driver instead of the binary one. Everything has been fixed.

I'm not an expert, but the port may be occupied by another program.
