First, IntroBefore the gateway, many netizens concerned about how to implement the interface. To understand the change of the next machine variable, it is how to trigger the human-machine interface animation in one step.This step-by-step trigger is essentially a bulk data change (DataChange) event for the variable group (s), which raises the variable (TAG) value Update (ValueChange) event, which eventually triggers an animated script (Action) of the e

You can try to clear the browser cache and access your FTP to see if you can log on Cause A server (not necessarily a Web server) serves as a gateway or proxy to meet customer requirements (such as a Web browser or our CheckUpDown robot) to access the requested URL. This server receives an invalid response from the upstream server to fulfill its requirements.Fixed 502 errorsGenerally, this problem is caused by poor communication between IP addresses o

Problem descriptionAfter initial troubleshooting, the application gateway itself works fine and also excludes the latency of the Azure platform network. The behavior that occurs is usually a partial URL response is normal, a partial URL response is slow, or HTTP Code 502 is returned.Problem analysis Determine application access and response by analyzing access logs (see: Backend Health, diagnostic logs, and metrics for application
