Unable to access via HTTPS, OnCommand System Manager after SSL certificate Renew, FAS2240 9.1P20

Meadastian

Hello

We are trying to renew an expired Sysmgr certificate for access the Oncommand sys man. on a Fas2240 with ontap 9.1P20.

We used the netapp kb (https://kb.netapp.com/Advice_and_Troubleshooting/Data_Storage_Software/ONTAP_OS/How_to_renew_a_Self-Signed_SSL_certificate_in_ONTAP_9#), we checked all the steps. In this moment we have a new self signed certificate assigned to the manager SVM "fasclu" it is "Server enabled", but when browsing the mgmt cluster ip, or a singel node mgmt ip, we get a ERR_CONNECTION_CLOSED.

We have already rebooted one node, but nothing changes. If we enable the HTTP access, we are able to logon to oncommand.

Also a new certificate was issued but nothing.

Did you ever experienced anithing like this? The same operation with the same commands was issued on a FAS220 with same ontap and all went ok.

Thank you.

Sebastian, i think you should create a case

The logs shows the following and we have also seen expired vserver certificates

Look up these KB's

ERR_CONNECTION_CLOSED Observed when accessing System Manager
How to tackle common issues with trying to upload image into System Manager

After upgrading ONTAP, System Manager and API are failing

thank you hamdani, but the first KB link to the kb that we used for renewing the certificate, the second kb link to third kb that say to renew the certificate as showed in the first kb.

We have already searched the kb's for this problems, but we did not resolve.

Also we have already renewed an expired certificate with this kbs with no problem on a Fas2220, it'only the 2240 that has the problem...

Any idea? thank you very much. i appreciate.

hamdani

let us confirm the latest certificate serial number and make sure "server-enabled" for ssl show command, also confirm the cluster health

example: Putty into cluster console and please confirm the commands below

cluster show

cluster ring show

sec cert show -common-name fasclu
ssl show -vserver fasclu -fields vserver,server-enabled,common-name,client-enabled,serial
services web show -vserver fasclu -name sysmgr

Meadastian

Thank you

in the meantime we tried to use our internal CA for generating the certificate but same result

here the output of the commands (i am hiding the internal domain name only)

hello Hamdani, do you have any other idea?

We have 3 netapp, this fas 2240 is the only with this type of problem. It is very strange that we can't restore the https access. are there any log that we can analize for troubleshoot this problem?

thank you very much. Sebastian
