Error status code 200 while hitting landing-page of ShinyProxy

[dylancis]

initial comment moved to a separate ticket #159

[dylancis]

I believe this is also the reason why if you try top freshly open the /app_direct/ while using auth0, afte rlogin, you will get straight the following page:

You git F5 (refresh) anfd the app will show up.

We are using landing-page: /app_direct/<app-name>/ + Auth0 and users occassionally see the 200 error mentioned by @dylancis.

[dylancis]

@michaelhogersosis we are using the default landing-page in our side.

[dylancis]

This is happening even using the main index page and clicking on the app link without /app_direct/

[michaelhogersosis]

@dylancis, do you occasionally have users running into a 404 error as well? It is similar to the 200 error you describe, in that the application will show up after refreshing the page

[dylancis]

@michaelhogersosis I used to indeed after a new deployement - now our process tries the app once after a new ShinyProxy deployment.

Hi @fmichielssen I have renamed the github issue as this was two different issues one is feature request:

• loader screen meesage while /add_direct/ is launched No loading message when /app_direct/ Shiny App is launched (contrary to /app/ version) #159
• 200 error status code while loading landing page of ShinyProxy (the one here)

The url gets updated with the following - not sure what that means though:
http://shiny-dev.dbrsanalytics.local/error?code=qUAIPRpdMMUwJhO8&state=2BVOdnXqMXIwUH9k26SI6kBq7Tjqza6Bu9hhjwjyjoo%3D

@dylancis, interesting, we noticed a similar issue after a new deployment. Are you using Kubernetes? I had a feeling our image-pull-policy: Always setting was the cause

[dylancis]

@michaelhogersosis yes we do use k8s although we have the following set:
image-pull-policy: IfNotPresent

I have a user at another site who runs into this the first time they attempt to log in on a regular basis. I'm not using k8s, but I am using KeyCloak for authentication. Not using the /app-direct/ URL, either.

I have the same issue when i try to login the first time. The second time works well and i can access the main apps page.
I'm using LDAP for authentication and shinyproxy v2.3.0. (I'm not using the k8s and /app-direct/ URL).

Hi @PauloJhonny Can you check with ShinyProxy 2.5.0? 2.3.0 is almost two years old and there have been 6 releases since (with numerous fixes).

[PauloJhonny]

Hi @tverbeke. I'm having a problem when upgrading to 2.5.0 :(
That's why i haven't done it yet.
If i just change Dockerfile to get the 2.5.0 version, I can access the login page, but it is not responsive...

Since i customized shinyproxy templates (app.html, index.html, login.html, navbar.html), i think there's something to do with it... Maybe I need to do the customization again, but using the default template files.

Thank you.

EDIT: I upgraded shinyproxy to 2.5.0 and it seems the problem is gone.

Hi @PauloJhonny

Great to hear that 2.5.0 solved your issue!
As I believe that your question is answered, I'm closing this issue. Feel free to re-open it if you need more help.
