Prohashing Mining Pool Forums

Every 30 mins to about an Hour my mining rigs stop and I get this error message:
> 20:16:06 Authorization on Stratum Server Failed: Authorization failed because there are no coins available to mine for this algorithm.
> 20:16:06 All user mining pools are unavailable

I'm wondering what's going on? Everything was going fine since I started mining here last month and for some reason I been having this issue for about a day or so - It's hard to pinpoint the actual timeframe only because I thought it might of been my internet connection. Is anyone having the same issues or figured out how to resolve them? Thank you for your time!

It happened again:

I didn't have the emergency failsafe message, but I'm still receiving the messages previously mentioned, I wonder what's going on. My guess would be some kind of new changes to the cryptocurrency currently being mined or some kind of new fork, but these guesses are up to speculation.
