openssl pkey -pubout -in privatekey.pem | openssl sha256

openssl x509 -pubkey -in 0001_chain.pem -noout | openssl sha256

openssl x509 -pubkey -in 0000_cert.pem -noout | openssl sha256

You can't use chain for that.
You need the right cert.pem file.
[that matches that privkey.pem]

it is there in folder

Then perhaps there is a permissions problem.
OR
There is a TYPO in the file name used.
Please show:
ls -l /etc/ssld/*.crt

Your nginx configuration means dvslearn.crt but your /etc/ssld directory only contains dsrlearn.crt, like @rg305 mentioned yesterday.

it's not that. i changed the name and still getting error. i think it's either problem with openssl or cert file

99

Your server is sending out a valid certificate and chain. See this SSL Checker

Are you still getting the error from nginx? If so, please show the results of this command:

sudo nginx -T

(upper case T)

Please put 3 backticks before and after the output like this:
```
output of command
```

yes i think it's a problem with openssl or cert files. so uninstalled nginx and i compiled nginx with openssl. i created ssl again. it works now.
