im sorry for my rude comment earlier. but It dont have any gui. and yes we have tried changing network based on your suggestion, but it dont work.
No issues dude. I do verify each and every time before I post anything in tech board. Most of my posts has somehow contributed to the topic or helped OP in solving his issue, helped them in understanding simple commands on smart contracts etc. Also I don't post what comes to my mind, I do verify with older posts and issues in github before posting. Negative confirmations has been probably a common issue during server sync. Check out earlier issues raised in git and also if it doesn't solve your issue you better ought to delete the block headers. That might be one of the possible ways. If that doesn't solve either, you better need to wait for an electrum dev to answer your issue in github.
Check this out buddy
Deleting the block_headers in the .electrum directory to download it again does correct the unverified issue
P.S Is this issue raised by you?
