When i search for servers in the Multiplayer launcher, i can't see servers which are visible for others at the same time. In my case i am noticing this with the sr4l league servers. They have 3 servers online. i always only can see one of them at the same time. with hitting the refresh button several times, it sometimes switches between 2 of the 3 servers. the third is never visible to me. Other don't have this problem. For me it is like that since about 2 or 3 days. i had not changed anything on my PC at that time.
Is this still happening? With any connection issue like this, where you have the problem and others do not, I want to try not to waste any developer time by having them look at it, as it could be just an issue/have been an issue with your connection... So is it still happening?
I remember we all had the same problem at the time, it was a temporary problem with our servers, so no worries, its ok now.
