`Failed to restore: getCacheEntry failed: Cache service responded with 503` when using a fork of actions/cache

[osy]

I need to run a fork of actions/cache because the default timeout values do not play nicely with my caching proxy (it needs to cache the entire file before sending data back in a range request and so it will take longer than the default timeout values)

https://github.com/osy/actions-cache/commit/2fc65ffa9098d26fa9a7be100f1b81a97ff6341a

This had worked for a long time but recently, I get Failed to restore: getCacheEntry failed: Cache service responded with 503 which I suspect is because I am using a fork (pointing to this repo works fine).

Please either fix forking actions/cache or provide us with better control of the timeouts.
