Last few days my electrum wallet keeps on "synchronizing" and nothing change. ... The status is still "synchronizing" with blue arrows in the right corner.
My last received transaction there is 0. I've checked it in blockchain and the status of the last transaction is "received". But in my balance is 0. I guess, because my wallet isn't connected.
This appears to be a known bug as discussed in this thread:
