The OP was quite clear about this, "I have a stable connection on the bottom right of the DOT is green and i changed the connection servers etc .." What may be the problem is that the OP loaded the wrong wallet, another native SegWit wallet or legacy account. If this is not the case, then unfortunately he is the victim of the already well-known clipboard malware that changed the recipient's address and there is no help anymore.
The least likely cause of the problem, because unless it's versions below 3.3.4, all versions above will work identically when it comes to connecting to the server/s.
