9 minutes has passed after you posted this and I checked ethplorer and it works perfectly.
It's strange that everything works fine for me, I do not see any problems with it, still today there are problems, if you live in Russia, this is possible, because they are trying to block the Internet. If you live in another country, then the provider has problems.
It also works to me and I don't know why OP has problems with it.
What's the error you are getting OP?
