websocket 400 connection failed
hi,

i have created a python application that uses jupyterhub and has been deployed to kubernetes

the jupyterhub setup is a combination of kubespawner and saml authentication.

i want to deploy the same exact application to multiple kubernetes clusters (each kubernetes cluster represents a differe…
since the error is on websockets, it is almost certainly a proxy layer somewhere that doesn’t support websockets, which is different on the two clusters (i.e. between you and any jupyterhub’s proxy-public entrypoint, rather than any part of jupyterhub itself or any of jupyterhub’s own configuration)…
[@sensiblearts](/u/sensiblearts) has been working on a guide for libcluster setup (that will be put up on [powauth.com](http://powauth.com)). here’s a way to handle it: <https://github.com/pow-auth/pow_site/issues/10#issuecomment-533845299>

i’ve tested it locally with a k8s cluster, and it worked perfectly scaling up and down. if you push t… solution to my problem.

install python enabling framework and then do the rest of the installation as defined

python\_configure\_opts="--enable-framework" pyenv install 3.6.8

the issue was with wx and the need for a framework

when running a simple ws app

import wx

app = wx.app(false) # create a… a couple of things to check:

(1) make sure your file realy exists

(2) your file path does not seem to be correct full path, should it be something like c://users/…

(3) you can also try a relative path, namely, copying your tiff file to the same directory as where you start your jupyter. then, use… don’t worry, possibly you’re using mediasoup, just the name of the media nodes still being named as kurento media server.

to check if mediasoup is running, just ssh into one of the media nodes machine and execute this:

sudo su

docker ps | grep mediasoup

you should see a container using this image… hello and welcome [@jhmauritz](/u/jhmauritz).

yes, changing the variables should be enough to connect to the server, and using docker-compose is absolutely a viable option.

if the server is publicly available you should configure ssl as well, otherwise your connections to it won’t be secure.

mind that although y… hi yerhu,

i could imagine, that one of the two following scenarios may cause the issue:

you’re using an outdated version of tk-core. check in your configuration: core/core\_api.yml

you’re using a pipelineconfiguration, which is pointing to a local-path and includes a file like python\_interpreter, i… hi and welcome!

it’s not an open ondemand thing. you need to setup sshd to allow for hostbasedauthentication and generate some key pairs. this setups some sort of trust between 2 or more servers saying “if you’ve logged into one of them, you can login to the other directly”.

of course we use lots… hi [@petr\_kibukevich](/u/petr_kibukevich) 
issue has been fixed and deployed to cloud servers. please verify whether everything works fine now 
anton Hello Nanda, Basically you need to include the network drivers and the storage drivers.

+ You can find the drivers from Manufacturer site where you can filter the Category and download –

Like this – <https://snipboard.io/bQt5ER.jpg> the simplest solution is to install psi4 to a new conda environment. the point of creating a new environment is that different programs live in different environments. their dependencies can’t interefere with each other, but the programs can’t interact with each other, either.

i recommend you creat…
