Hi Duraibabu

Hope you are doing well and sorry for the trouble. As described the signature in the PDF is showing invalid.

Is this an issue with a particular PDF file or with all the PDFs with digital signature? Please try with a different file and check.

Would you mind sharing the version of the Adobe Acrobat Reader DC you are using? To check the version go to Help > About Acrobat and make sure you have the latest version installed. Go to Help > Check for updates and reboot the computer once.

Also, try to reset the Acrobat preferences as described in the help page https://community.adobe.com/t5/acrobat-discussions/how-to-reset-acrobat-preference-settings-to-default/td-p/4792082 and see if that helps.

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