Environment

Release : 16.x

Cause

DE64360

Resolution

Workaround:

Use a public signed certificate
Populate the internalURL as documented
- <webServer schedulerUrl="" capaUrl="" internalUrl="http://xx.xxx.xxx.xxx" sessionTimeout="" tenantTimeout="1440" sslType="implied" enableBroker="false">
Prior to 16.1.1 below workaround can help - A new system option is introduced which by default be disabled (with value '0'). When this option is enabled, we send a flag to playwright which intern sends a flag to Chrome to indicate ignore HTTPS errors. Hence any customer (On Premise) using self sign certificate will get the error by default and explicitly need to enable the option and below steps to be followed

- Stop all the clarity services
- Navigate to clarity_home\bin directory and run the below command
  - admin system-options -add PLAYWRIGHT_IGNORE_HTTPS_ERRS 1 -force
- Restart clarity services and now all the http errors will be ignored

Additional Information

Note:

This issue can also affect export to pdf in status report as that also uses playwright
Broadcom recommends to use public signed certificates as enabling to ignore http error will ignore all http error and not just for module where playwright is used like Status Report, Roadmaps etc
