Hi @Usman_Rasheed_Siddiq ,
Are you using Hosted n8n or on-premise?
Thank you
Hi @Usman_Rasheed_Siddiq ,
My recommendation is to uninstall and install back the n8n on-premise.
Please also restart the computer after uninstalling.
Let me know if this worked.

hi @Joao_Paixao ,
Thank you so much.
I cleared everything and ran it again. It asked me again for an activation key, sent an email and now it’s working properly.
The email said that the activation key can work within 14 days but I think i should have done it the very moment when I first install n8n.
Hi @Usman_Rasheed_Siddiq ,
I’m glad it worked.
Please mark my answer and the solution for your issue.
Thank you!
