Img to img generations not working?

Is it just me or is High Res fix, Face Fix and Img to Img variations not working? it was working a day ago, but now the process moves to generating status but then refund the buzz and just cancels. Been trying since morning, but not a single image went through with anything involving img to img process.

Apology if Civitai had already mentioned about this before in any post (in case if i've not read something somewhere) or my generations are being denied without error or warning.
