Thanks again, Neemobeer. I usually prefer Duck Duck Go with my browsers (both FF and Vivaldi are set that way). I looked in the settings for Edge and couldn't locate any info on the search engine being used. I'm guessing it's Bing, or whatever MS prefers to use.
I also noticed that the "Error 502" message only occurs if I'm doing a search. Clicking on my bookmarks, everything is OK. I was going to change default browsers, but I'll keep Edge as my default since it works OK for the most part. If I can find a way to change the search engine, I'll do that. I think you really hit on the answer, as it seems the search engine in Edge is probably the culprit
