You need to connect to our 为屁嗯 server use your 为屁嗯 username 8631, after that you can open the IPMI page
http://172.11.165.64/, there you need to use the IPMI username/password, its can be found on device page.
Please be sure you have only one username in your 为屁嗯 client configuration to connect our VON server.
According to previous logs I see you configured your client to authorize with correct username (8631) and after that trying the IPMI_6526 user in 为屁嗯.
This is incorrect. Please check your 为屁嗯 client configuration
