There has been something strange on my page for a few days, and I don't want my efforts to go to waste. Can friends with any information help?

For the past 4 or 5 days, my posts are dropping very slowly, and the engagement is progressing very slowly. When I look at the Gomtu side, it has been giving an error for a week; it wasn't like this normally. Mindshare was also high, and my rankings were visible. It's been like this for a while now; is there anyone who can help, what could the problem be?
