Can't authenticate to Proxmox

[StrugglingStarWind]

Hi All,

I've been trying to convert VMs from vCenter to Proxmox but every time I try it fails with this error:
Facility ???ERROR: Proxmox::WrapperProxmox::WrapperProxmoxImpl::Connect: Failed to parse JSON response

Here's the entire log in case that's needed. Please let me know how I can get past this so I can use the product.

I believe it's more related to Proxmox than StarWind V2V.
I think the easiest might be copying the VMDKs and deploying that VM in place.

Can we please get some assistance troubleshooting this issue before immediately passing the buck off and telling us to "do it manually"?
After reading many forum posts here, it seems that's the go to reply for anything but the simplest of issues posted. Why is that? The whole point of ANYONE running this software is to prevent having to do it manually.

All I was trying to do was deliver the fastest solution so you don't wait for me to discuss things internally/check logs.
Could you please let me know the version of Proxmox you have?

I have this exact issue. I’ve tried with both a Proxmox 8.4 and 9.1 host, same issue, ‘failed to parse JSON response’. Works fine from an ESXi host a HyperV host. Might it be anything to do with having a specific version of JavaScript installed?

[yaroslav (staff)]

Thanks for your update. I will log an internal request to check.

[yaroslav (staff)]

Please try this one https://starwind.my.salesforce.com/sfc/ ... 1WvfQ3eHKE.

Installed the updated application, and it worked perfectly from ESXi to PVE 9.1. No issues logging into either the ESXi or PVE hosts.

Thank you so much!
