Since you say you have a good internet connection, the problem is probably with the server. You can simply try connecting to other servers.
Just to add to this to probably narrow it down more I've been using a node from this forum for quite long now obviously because of a much smaller relay fee. Any suggestions why I'm getting a slow sync?
Is your purpose to broadcast transactions with a fee rate of less than 1 sat/vbyte?
If that's the only reason why you are connecting to that specific server, you don't really have to do that. Currently, many other nodes are accepting sub 1 sat/vbyte transactions, and even if you let Electrum connect to a server automatically or you choose a random server, there's still a very good chance that the server accepts such transactions.
