Hi everyone,

for the first time one strange message appear after login windows in Vault Pro 2026 client:

Only one usage of each socket address (protocol/network address/port) is normally permitted.

How can I fix this?
Thanks everyone.

Can you post an image of this message?

What operating system is the Vault server installed on?

[bruno_milano]

Yes,

this is aìone image of the error:

On Vault Server is installed Windows server 2022.

Have your IT department log onto that server and see whatelse is listening on port 80.

1. Open CMD and type: netstat -a
2. Take a look in the Local Address column.
3. Look at the port portion.

Okay, I can ask.
But the strange thing is that this message only appears on one client; all the others work without problems.
