Temporary failure in name resolution in ssh command

in flag
J R

I haven't used my Ubuntu WSL in about 4 months, today I opened it up to use ssh to connect to a server for one of my classes and I get the following error. I've tried the other solutions that I've found here on stack exchange etc with no success. As well I need a permanent solution as this is going to be used on a daily basis. I don't quite understand what happened for it to now suddenly not work and would appreciate some sort of answer to this. I also cannot run 'sudo apt update' either.

You should edit your question with the details you left out. You should include the details of your research, what you've tried, and the results of those attempts showing how/why it did not work for you. Include also the output of `sudo apt update`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
