In order to resolve this issue you will need to install the required libssl file into the shared folder or install it:

Please use these instructions to install it:
​
CD into this folder /usr/lib/arm-linux-gnueabihf/
​
Then you will need to run the following command to view all softlinks which are created for the shared libraries:
​
ls -l /usr/lib/arm-linux-gnueabihf/libssl*

and remove the softlinks which are created (the names for the libraries might be different in your case):

rm -rf /usr/lib/arm-linux-gnueabihf/libssl.so.1.0.0 /usr/lib/arm-linux-gnueabihf/libssl.so.1.0.2

and then install missing library into the shared folder.

cd /usr/lib/arm-linux-gnueabihf/
​sudo wget http://security-cdn.debian.org/debian-security/pool/updates/main/o/openssl/libssl1.0.0_1.0.1t-1+deb8u10_armhf.deb
sudo dpkg -i libssl1.0.0_1.0.1t-1+deb8u10_armhf.deb

and then once this is done, then you might try to restart the Pulseway service to see if this file is picked up automatically. If that doesn't happen, then you will need to reinstall the Pulseway on this system:

Navigate to your home directory:
cd /

Uninstall Pulseway
dpkg -r pulseway
​
Start the installation process:
​dpkg -i pulseway_armhf.deb

Then if the installation is successful start the Pulseway service:
​systemctl start pulseway

And then register the Pulseway agent with your Pulseway account:
​cd /usr/sbin
pulseway-registration
