Solved: Re: PZT API preview request returns SIP 500 Internal Server ... - HP Support Community

claols · ‎07-15-2026

Hi.

Since ~10:00 CEST today, we've gotten the following error

 {"statusCode":500,"error":"Internal Server Error","message":"Internal server error"}

as a response when running an API request:

GET https://api.ztp.poly.com/preview/devices?limit=1000

Yet, when checking the status page https://status.plcm.vc/, there are no issues with the Zero touch services. Is there any ongoing issue, or has the API been changed?

Could you check this?

Hello @claols ,

Welcome to the HP Poly community. This is just a peer-to-peer community forum and not HP Support.

Please open a Lens Mopinion Bug via https://lens.poly.com/appfeedback

If no other volunteers reply, I suggest you contact the HP Support organization in your region. Details are in my Signature.

Best Regards

It's a hail mary shot 🙂

The URL you sent isn't working. Just references the following:

Hello @claols

I just realized this is not LENS related but ZTP.

I check with the team.
