@nicofierrov , I'm sorry to hear it still isn't working.
What versions of Google Chrome and Firefox are you using? I've tested on both of these browsers, and it seems to be working fine for me.
Are you able to deploy using the link below? I noticed your screenshots are in Spanish, this will force the app to load in English. This shouldn't make a difference, but without seeing a network log, I can't be sure what else could be at play.

If the link above doesn't work, can you DM me a log of the network traffic when you try to deploy? I'd like to debug the process to see what is going on.
