HTTP request causes "Connection lost"

I have a HTTP request node that scrapes about 100 websites and then goes into a extract HTML content, but when I run it it always crashes and causes “connection lost” on n8n and if I stop the workflow, it glitches out and then when I go to refresh the page I get “Workspace offline (503)”.

No idea what is going on. It was working fine just a few hours ago but now its all broken, It only works if I do like 10 websites. I’m new to nPreformatted text8n, and don’t really know / understand how everything works.

Thanks for any help.
