received the following error message for site I use often ( 500 - Internal Server Error )
Since you’re providing absolutely no additional information and not even including the problem website, we can only guess at the most general suggestions:
500 - Internal Server Error is usually generated by the website you are visiting indicating something is wrong with that website. Unless you are getting this error for many websites, it is probably a site specific problem.
This is unlikely to be a CD issue, and posting here is unlikely to help. Rather, you should follow up with the website you were trying to reach.
