Hello,

Do you have this components in your PE?

You can install them from Forge.

The things that's been done so far: 

- Service studio reinstalled multiple times.

- Solution with all modules republished.

- Each of the template application republished and reinstalled later on.

- All of the providers and consumers republished.

- Platform server upgraded following the steps of the Checklist for OutSystems Platform Server Installation.

None of the above mentioned things helped with the issue.

HI @Marius Raškevicius

I think may your environment version outdated, can you try to update your version in the website, may be its helps you, suppose if this not works then you need to rise the ticket for the support from Outsystems teams.

Thank u

Hi Marius,

Something else you can look into: Does your environment have a valid SSL certificate?

Cheers,
Tiago Simões

You may also want to take a look into Service Center error log.

Thank you @Tiago!

Certificate is valid until the end of 2020.

Regarding the error log it shows the following error message, but only when publishing something. Can TemplateManager be related with this?

Hi Marius,

That "localhost" looks fishy. Make sure in Service Center > Administration > Environment Configuration the hostname is set correctly and Service Center > Administration > Deployment Zones > Global also have the "Deployment Zone Address" correctly set.

Cheers,

Thank you, everyone, for the replies. 

What helped for us:

1. Removing and reinstalling all the UI frameworks (OutSystemsUI Web, OutSystemsUI)
2. Removing and reinstalling all the templates (OutSystems UI Templates Mobile, OutSystems UI Templates Reactive, OutSystems UI Web Screen Templates)

We don't know what exactly was corrupted there, but we can create new applications now.
