Cycles through three different errors, most of the time its network connection issue, sometimes too many requests (rare) and sometimes authentication failed, check API settings, and i got both my stuff from the links in settings
Thats strange :/ I suggest try getting new API keys, Set Image Model to ICBINP and Sampler to DPM++ 2M. Test Connection button to Cofirm settings. Hit Save Settings and refesh for good measure.
