I apologize if this is a rudimentary question, but I searched for it in the forums and didn’t find anything that answers my specific problem, only adjacent problems.
When I click preview I get the broken file frown icon and when I hover my cursor over it the error message reads “previewer.adalo.com sent an invalid response”
This is BEFORE the start page of my app or ANY other content is available. Therefore, I cannot preview ANY aspect of the app I am trying to build on ANY of the available phone and tablet templates.
Welcome to the forum!
This is something which shouldn’t happen
I’d suggest doing the following:
- try to open the app builder and launch preview in the browser incognito window (so that no previous cookies and cache exist)
- try to open the app builder in different browser
If the problem persists, it might be a good idea to submit a support ticket here: Submit a Support Ticket
Also, it is worthwhile to check if the problem is related only to one app or all of your apps.
Best regards, Victor.
Thanks for your speedy reply!
I tried to use the preview mode in incognito on chrome and got the same error message. Then, I cleared my cache and cookies and tried again, same error message.
Using Safari, I get no error message but the preview phone screen is just black.
Using a fresh install of firefox, I am getting the following message: Secure Connection Failed
An error occurred during a connection to previewer.adalo.com. SSL received a record that exceeded the maximum permissible length. Error code: SSL_ERROR_RX_RECORD_TOO_LONG
I am trying to develop an app that serves as an ala carte learning tool for my biology students, so I am working in the free version until I verify that it works and does the things I want it to do, I was then planning on purchasing a paid version. However, if I can’t test it I may abandon the effort.
I will now go try and build a dummy app to see if I get the same errors and then get back to you.
Sure, I understand - without possibility to test it makes little reason to upgrade
From my point of view, it will be difficult to do anything from a user/maker side with such error. As I said, I’d advice submitting a support ticket to get a response from Adalo’s support team.
Testing on a dummy app is useful anyway - at least you’ll understand whether this is related to your account in general or just to a single app. This information will also be useful for support.
Best regards, Victor.
