My Cloud PR4100 / EX2 Ultra Login My Cloud OS5 504 Error

Hello Team

I find most of model My Cloud PR4100 / EX2 Ultra have login issue with 504 Gateway Timeout issue since March 10 2024. I try login my cloud OS5 on device or PC or Mobile Phone but have same error .I try to enter error password but it could show my wrong password but i input right password it wait a long time and page show The gateway did not receive a timely response from the upstream server or application. I think cloud service may have some module issue need WD official engineer check it .

All device model include My Cloud PR4100 / PR2100 / EX2 Ultra with firmware were 5.27.161 (January 22,2024)
