502 Bad Gateway error and white screen when opening Admin Console

Version Affected:  19.07+

Description:  

When attempting to log into the Admin console, only a white screen loads. 

Dev Tools (F12) shows 502 error when attempting to open

https://localhost/httpproxy/api/v3/sysinfo/ping

Attempting to navigate there manually, you see a 502.3 error

Cause:  

Netmon can be used to check the actual cause but typically it is that the binding cert has a problem. 

Resolution:

Acquire a new certificate.

1. Open IIS

2. Click Default Web Site

3. Click Bindings

4. Select https and Click Edit

5. Click Select

6. Choose the new Cert

7. Click OK

Special Considerations:

This issue could also appear after binding a certificate to IIS. Check if the full certificate chain is in the correct locations on the certificates console. The intermediate and root certificates would need to be there or else you will receive a 502 error as well.

If the above doesn't fix it, please perform the following steps in order to get a log that shows the root cause

1. Open an Admin Command prompt

2. run
netsh trace start scenario=internetclient capture=yes persistent=no level=verbose tracefile=c:\temp\net.etl

3. Reproduce the issue

4. Run 
netsh trace stop

to stop tracing

5. Grab C:\Temp\net.etl and send it through to support.
