Hi Yogesh

 

Hope you are doing well and sorry for the trouble. As described you are getting the message for invalid signature on the PDF file.

 

As mentioned the document is signed by Global Sign DSS, please try to sign the PDF via Adobe Acrobat/Raeder DC application and check if that helps.

 

When you receive a signed document, you may want to validate its signature(s) to verify the signer and the signed content. Depending on how you have configured your application, validation may occur automatically. Signature validity is determined by checking the authenticity of the signature’s digital ID certificate status and document integrity

 

For more information about validating the signature please check the help page https://helpx.adobe.com/acrobat/using/validating-digital-signatures.html

 

Hope it will help

 

Regards

Amal
