2. Troubleshooting

a. Print ps -ef to confirm the web process is runing.

Web process is running normally.

b. Collect the gatherlog to check

Run environment parameter to make it possible to execute mdf command.

export LD_LIBRARY_PATH=LD_LIBRARY_PATH:/opt/bts/lib:/opt/usr/local/lib

export PATH=$PATH:/opt/bts/bin

Run gatherlog collect commands:

mdf -n oamprocess gatherlog

Query current version and old version:

ls /appfs/package/now/

ls /appfs/package/old/

From the log, we see the flow “web foreground<-------->web background (lighttpd)<-------->web (websocket)<--------> OamProcess is ok, and heartbeat is normal.

c. Open another tab and put https://192.168.0.120:20000 , click “Advanced” and accept the risk. Then can open https://192.168.0.120 .

Summary: Enter 192.168.0.120 with port 443, if the certificate is incorrect and it will prompt. But with port 20000 will not prompt. Therefore, input clearly https://192.168.0.120:20000 to make the browser prompts. This problem will not occur if the certificate is correct.

3. Solution

Temproray solution: Open another tab and put https://192.168.0.120:20000 , click “Advanced” and accept the risk. Then can open https://192.168.0.120
