Learning and development shortcut link is not working

Hi Experts,

We have a portal with the below url

https://xxx.yyy.zzz.net/irj/portal   where ESS  is implemented

ESS contains  Learning and development which is based on BSP

End user went to some course and on right click he is getting the copy shortcut with the below url

https://xxx.yyy.zzz.net:40001/sap(bD1lbiZjPTUwMCZkPW1pbiZ2PTcuMDIxMyZpPTE=)/bc/bsp/sap/hcm_learning/leso.htm?plvar=01&otype=D&objid=345621&CORE=trainingtype.htm&SESSION_TOKEN=sdfhsdfhfdhjsds==

User sending this url to some other users so that they will directly open the course. User is sending the above shortcut url to oher users via email.

When the other users opens the shortcut url via email, it is asking credentials. After giving credentials, we are getting the below BSP Exception error.

How can we see the root cause of this error.  In the NWA I am not seeing any logs.

More over in the portal url there is no port. But in the shortcut url there is a port.

Can you please throw some points so that I can analyze more on this.

Thanks&Regards,

Raghu
