Problems with updates

Hello everyone! I have a problem updating my virus definitions. A pop-up box appeared and said that avast is unable to update virus definitions so I manually updated it. But during the download process, this error appeared. I tried uninstalling and re installing avast but it did not work. Do you have any suggestions in solving this problem? Thank you.

Try again in 2-3 hours, the server maybe temporarily offline.

Thank you! definitely will try that.
