Could you try to use 1.23-nightly? Maybe it has been fixed.

[wxiaoguang]

By the way, if there are 500 errors, there should be other error logs. It seems that you didn't collect the related error logs in the report.

dear @wxiaoguang today I will try 1.23.6
here is a previous line before error with 12:40:09 and 12:40:17 timestamp:

[wxiaoguang]

I think it duplicates with #31600 and should have been fixed in 1.23 nightly by #34033

[wxiaoguang]

today I will try 1.23.6

By the way, the fix is not in 1.23.6, please use 1.23-nightly (it will be 1.23.7 soon)
