Unbale to access the etherpad through jitsi meet

I had installed the jitsi meet and etherpad

Both service are working
from jitsi toolbar the etherpad is also there
Apart from this I had added base url of etherpad in domain-config.js(port is open)

and also configured with nginx as per the below in sites-available/domain file before the end of ssl block(in second server block)

And then whenever i am clicking on “open shared document” nothing is happening there is wrong. Put the IP address where etherpad is running.

I had tried but same issue nothing is happening
