Hi, is there any way to overcome this issue when trying to download a project on QGIS? Thanks

[PeterPetrik]

hi @Tom-Telenova we would need some traceback of the error

Thanks, any change you are behind firewall or any corporate restriction to access our servers?

• which windows version do you use?
• which QGIS version do you use?
• do you use latest Mergin Maps plugin?

[Tom-Telenova]

Hi,

It's Windows 10 QGIS 3.16.15 Mergin Plugin version is 2022.5

[PeterPetrik]

We support only latest LTR and PR , so can you please try to update QGIS to Version 3.22.9 LTR and see if the error still persists?

[Tom-Telenova]

Hi Peter,

I've now got the QGIS Version 3.22.9 and getting the same error:
