Heya @TheBlessedKettle
Give the BisectHosting support team a shout they can set you up with instructions on running an MTR, have a look at your panel, and help pinpoint where the connection issue is taking place, and if need be, get your server set up on a different node. They're staffed 24 hours a day and usually take just a few minutes to respond.
