Problems with Perforce

Hello all,

We are a startup currently working on a project set to be released soon, however, lately we have been facing a lot of issues concerning source control that are causing delay and problems in our work flow.
We have lately decided to set up source control using Perforce, locally. We are using 1 PC as storage for all changes, and we are working on 5 others, 4 of these 5 are working perfectly fine, however, the remaining PC is unable to connect to Perforce, it is generating the following error:

Connect to server failed;
check $P4PORT.
TCP connect to :`1666
connect: : WSAEACCES

We have tried connecting it using the same methods we did with the others, the problem seems to only happen when we try to connect this specific machine. Also, for some reason when we try to connect to source control inside UE4 editor on this specific machine, and unlike all other machines, showing different default “Source Control Login” information, it is also unable to automatically find the workspace that we created inside P4V, although we tried entering it manually, it still did not work.

Any help would be appreciated,
Thank you.

Edit: We figured the issue out, there was a connection bandwidth limiter software that was running on the PC and it was limiting connection and bandwidth usage on P4V.
