I can't upload big files to gmod with it cutting off the connection 60% of the way thru

Like the title says, I can’t seem to upload a file without it being interrupted and it being reset back to 0%, after that it gets back up to about 50% and I get a connection reset error in google chrome. Garrysmod.org just cuts off my connection for the upload and I have to start again to only see it’s doing the same shit again.

Have you tried a different internet browser? There are others.
