Or what he meant was all 4 wouldn't connect but then 3 finally did but you just decided to say something rude to make yourself feel important?
Do you even read my first post? The other 3 are only able to connect after the message "your village has been raided" which made me lost a lot of resources from full collectors and especially drills that i want to save at all cost, and i was very angry for that since i did nothing wrong. I tried to log in.
Definitely not a server problem, if it was, we all would have not been able to connect.
Make sure you have a stable internet connection, try clearing the cache, even reinstall it. THis has nothing to do with SC, it is about your device and connection
If the problem was with SC, then others would have been having the same problem.
If it was starting loading, then stopping with the bar part way across, one possible issue could be that your memory card isn't properly seated, and so the device was unable to read it properly.
Then, you get so frustrated you start hitting the device much harder than usual, and that could have bumped it back into place.
[edit]
Hadn't seen your later post saying it had happened on 4 devices to start with, and now just one.
IN that case, definitely a network issue of some sort. Clash does seem to need a better network signal than many things do.
