I am seeing "ContentTypeError" errors in the log

[snigehere]

Describe the bug Since moving from the https://m.ginlong.com/ to https://www.soliscloud.com/ I notice it takes an hour or more before data appears following a restart. I have turned on debug and checking the log I see a lot of records: DEBUG (MainThread) [custom_components.solis.soliscloud_api] Error from URI (/v1/api/inverterList) : ContentTypeError(RequestInfo(url=URL('https://www.soliscloud.com:13333/v1/api/inverterList'), method='POST', headers=<CIMultiDictProxy('Host': 'www.soliscloud.com:13333', 'User-Agent': 'HomeAssistant/2023.4.6 aiohttp/3.8.4 Python/3.10', 'Content-MD5': 'Pf6YJAUHEPtLXSHoRiWfrg==', 'Content-Type': 'application/json', 'Date': 'Sat, 22 Apr 2023 14:40:21 GMT', 'Authorization': 'API ***:**+**=', 'Accept': '/', 'Accept-Encoding': 'gzip, deflate', 'Content-Length': '35')>, real_url=URL('https://www.soliscloud.com:13333/v1/api/inverterList')), (), message='Attempt to decode JSON with unexpected mimetype: text/html', headers=<CIMultiDictProxy('Date': 'Sat, 22 Apr 2023 14:40:23 GMT', 'Content-Type': 'text/html', 'Content-Length': '166', 'Connection': 'keep-alive', 'Via': 'HTTP/1.1 SLB.9')>) 2023-04-22 15:40:24.293 WARNING (MainThread) [custom_components.solis.soliscloud_api] No inverters found 2023-04-22 15:40:24.310 WARNING (MainThread) [custom_components.solis.service] Failed to discover, scheduling retry in 60 seconds. 2023-04-22 15:40:24.313 DEBUG (MainThread) [custom_components.solis.service] Scheduling discovery in 60 seconds.

This could be related to the API issues that seem to be occurring at the moment. I'm only getting sporadic connectivity to the Solis Cloud API.

Looks like the inverterslist api endpoint is returning a lot of 502's at the moment.

Very sporadic connectivity at the moment. This is part of my home-assistand.log...

Does anyone have any news on this? Is there another discussion thread somewhere?

Could be related to the API errors that are still occurring at the moment - https://github.com/hultenvp/solis-sensor/discussions/280

[viking2010]

Solis have fixed their API issues now it would seem, so could you try again and see if this has now fixed your problem? If it has, hopefully this open issue can be closed off.

looks like the high failure rate stopped at 05:38 GMT today ... in the 6 hours since then I have only seen 4 errors .. this is typical of the 4 I have seen:

I can live with that as a failure rate .. its way better than before.
