How to solve the problem of freezing when connecting to IB from some computers?

Question

1C-Enterprise

Good afternoon.

There is a 1C cluster (platform 8.3.12.1790) from one working server. It contains an infobase located in the MS SQL database.
There is a distributed network from the head office and many departments.

Problem: clients connect to the server normally from the head office, but when connecting from remote departments, the connection freezes at the 1s splash screen (waited for an hour and a half - nothing changes), it does not give errors, there is no load on the processor, disk, network, memory. Channel 40 Mb/s. There is the same configuration on the same platform, raised on different equipment in another department - no such problems.

Tell me what could be the problem?

Answer 1

If the client-server base hangs on the splash screen even before authorization, then in most cases the client cannot obtain a license, either locally, over the network, or from the server.
What client licenses are used (software or USB) and how do clients get them?

Answer 2

Use a terminal server at the head office. Remote clients will connect via RDP.
This scheme has been the de facto standard for a hundred years.
An alternative option is to publish the application on a web server (in the same place, at the head office) and work with remote clients through a browser.
Almost no one practices connecting directly with a 1C client via the Internet to a 1C server.

Answer 3

from the head office, clients connect to the server normally, but when connecting from remote departments, the connection is
