Litecoin Core stuck "Syncing Headers" (97.3%)

Hello. Has anyone else experienced this since Litecoin Core? I haven’t been able to access my wallet because it’s stuck at 97.3% progress. Under “Number of Blocks Remaining” it only says “Unknown. Syncing Headers" and has been stuck in this state for hours. I am using the latest Litecoin Core wallet version which is installed on an external portable hard drive. I have Windows 10 pro operating system.
Can you help. Thanks.
In my appdata folder i see at the bottom of the “debug.log” file this informations:

It looks like your wallet isn’t connected to any other peers. Are you sure your ISP isn’t blocking Litecoin related traffic/ports? Have you also tried closing and reopening Litecoin Core?

I closed and opened it several times Litecoin Core. I installed a new wallet last night and for now it is syncing. There are about 480,000 blocks left. I want to warn all customers of the forum! After I wrote about my problem in the forum, three people wrote to me in a private message, who pretend to be technical support and want to provide them with the wallet.dat file and my password!
Scammers refer to three different links! This is an attempted scam!
