[Bug]: immediately logs you out when editing "Verify peer cert by name" field

Before you submit

• I searched existing issues and did not find the same problem.
• I am using the latest available PasarGuard version, or I included the exact version below.

PasarGuard version

v5.1.0

Installation type

Docker Compose

What happened?

In inbound settings, when editing an existing inbound, whenever I try to edit the "Verify peer cert by name" field under tls, it immediately logs you out. Even if you duplicates that inbound and try again, same thing happens. I am not quite sure what is prompting this, but pretty sure it's a bug.

Steps to reproduce

1. go to Nodes > Cores
2. click to edit an existing inbound setting
3. under tls, click on Verify peer cert by name
4. try to type something (if successful try to save the config) and it will immediately log you out from Pasarguard.

Expected behavior

Being able to edit "Verify peer cert by name" field.
