Connection errored out issue

[AIGenLab29]

hello, since yesterday morning I can't use automatic1111, it was working perfectly, now when I start the webui it loads the interface but I can't update the extensions, create images, change checkpoints and more, it loads endlessly.
at some point a red box appears saying "connection errored out".
I tried some fixes I found on the net but none of them work for me.
i can't figure out what happened, i didn't touch anything.
