After my setup was gone in my app and my sensors in HomeAssistant are all "unknown" for 2 days now, i saw that
a) the foxesscloud.com routes now to a v2-version, where no API-Key-Settings can be found and
b) in the v1-version it says: "Number of calls per day:0 Remaining calls for today:0"
I needed to add my inverter once again in the app. After that it appeared in the v2-dashboard.
Is the openAPI gone by now?
I can confirm I'm seeing the same error on my foxcloud HA test.

if using https://github.com/StealthChesnut/HA-FoxESS-Modbus I believe this project is no longer supported or maintained. Best to integrate using Modbus.

Did you update HA to the latest version about 2 days ago? I believe I read the latest HA breaks this integration.

Rebooted my HA and mine is working again as normal. Have you tried a reboot?

I've just run a test and am not having any problems accessing Open API.
Sometimes, Fox move servers and this changes the IP address - in this case, you may get an error. The integration then keeps retrying to connect. Please do a refresh and ensure your DNS records are up to date.
I am not seeing any re-direction of the web site between v1 and v2 user interfaces. The default for me is v1 and the v2 logins remain the same. These v1 and v2 interfaces do not change the end points used by Open API.
If you are still having problems, it may be best to check or raise an issue specific to the cloud integration: https://github.com/macxq/foxess-ha/issues

HA Cloud using OpenAPI is working for me, I have a test system working 24/7 and there have been no outages.
Make sure you have the latest version of the integration (v0.46) as that implemented a fix for an openapi change.
If you have 0 api_calls remaining in your profile you will need to wait until the remaining calls gets reset at midnight before you can access the OpenApi again.
