I cannot access the HP Aruba 2530-24G switch over http, ssh, telnet

Since you don't provide the URL to replicate the problem I can only speculate what the reason might be. But chances are high that your server is misconfigured and does not sent the required chain (intermediate) certificates, i.e. some chain certificate is missing. Desktop browsers often work around this issue but other clients will usually fail.

To verify my speculation check your site against SSLLabs and look out for reported chain issues.

Update: according to the comments of the OP at this question I was right. SSLLabs complained about "This server's certificate chain is incomplete" and also set the grade to B because of this.

Hello @LuisRM ,

There are lot of below errors:

W 07/22/21 16:37:05 05604 activate: EST enrollment with server failed because of
CACERTS curl error.
W 07/22/21 16:32:05 05604 activate: EST enrollment with server failed because of
CACERTS curl error.
W 07/22/21 16:27:05 05604 activate: EST enrollment with server failed because of
CACERTS curl error.

What is the status of the device in Aruba Central?

Have you checked if everything is fine from firewall side, no blocking?

Is there any possibility to reboot the switch or uprgade to latest software version?

Please share 'show activate provision' output?

Thanks!
