It takes a while for your node to recover from suspension. You need to succeed several audits before that happens. If you’re certain the issue is resolved, it will get out of suspension in a while.
I just created this feature request to get us some more insight into the score used for suspension. For know all you know is whether or not you are suspended. With the score we could know how close you are to recovering from that. You can upvote the idea if you like it.
