Warning certificate chain not correctly formed in certificate

L2 Linker

Hello All


I have imported a cerfificate into the PA as a PFX. I have also import the intermediate certs and root CA. The cert is signed by Go Daddy with 2 intermediate certs and a Root CA.


All imports fine, but when I get up global protect portal and use the imported cert (from the pfx) I get an error which says "Warning certificate chain not correctly formed in certificate"


Thanks everyone 🙂




@Nick.Spender You have to import it correctly before you can export it in a way that's helpful. If you export it now, with the chain incorrectly formed, I don't know what the reprocussions will be. 



I just exported as a PEM from the firewall and the order was completeley wrong. So yes you are correct. I reordered them correctly. Removed the certs from the PA and reimported. But it only shows 1 cert once it finished importing?

Seems like the chained cert is somehow wrong, my guess would be that it's not the correct intermediate(s). 

If you can just open your final cert in the list (the Wildcard cert) into a Windows system or else pull it up in a browser that displays the cert with the chain, you can export each of those and be totally sure you've got the right set of certs.


If you need additional help getting it to work, I may not be able to continue to reply and you might want to open a support case.


Best of luck!



Hello, I seemed to have fixxed, using a different method. So I have the cert import into my windows machine with the private keys. I then exported the certs as a *.p7b and selected include all certs in the chain. Sure enought in winodws the order is wrong. wheather im reading into that or not is a different quiestion. 


I then imported my pfx cert back into the PA. Then exported it as a PEM with the private keys. I copied the private keys into a text file and saved it. i then remove all certs aparted from my domain cert. 


I then removed all certs from the PA, I thern imported the cert back into the PA as a PEM and seletected the "key File".


Then imported each of the Intermediate CAs (2) as .cer


No errors when commiting, globalprotect portal webpage shows secure and green in the url bar. Global Protect connects fine with no errors.



Dose the above sound OK to you?

@Nick.Spender thanks. That worked..
