I have a weird error in my Developer instance: since a couple of weeks I can't install apps anymore. Regardless of the browser or computer that I use, after agreeing on the terms & conditions, clicking login, and confirming my password, I get redirected to login.salesforce.com. If I login I just get into my normal Salesforce instance and the application has not been installed. 

I recorded a 1-minute video that shows the error:

Thanks for any tips!
