I have installed and configured AppRTC, Collider, turn-server successfully.
But I am facing an issue of Websocket Error. Google chrome console errors are as follows:
Initializing; server= undefined.
apprtc.debug.js:5583 1.413: Initializing; room=undefined.
apprtc.debug.js:5583 5.209: Opening signaling channel.
apprtc.debug.js:5583 5.390: Got access to local media with mediaConstraints:

apprtc.debug.js:5583 5.584: WebSocket register error: WebSocket error.
apprtc.debug.js:5583 5.636: Joined the room.
Following is the screenshot of WebSocket error, which I am facing
Collider and AppRTC are on Google VM instance and I have used my own turn-server which has been setup on AWS EC2 instance.
Please help me to resolve this issue.
Is there any setting in Google APP engine, where I deployed an APP?
Advanced help would be appreciated !

ABP version 4.4 APP with identity server with angular EF core
my angular client send the username and password to identity server that is part of my abp application (mean same URL for api and identity server) that returns me token but after very next request for "api/abp/application-configuration" return with CORs error.
same application work for QA local environment with local config.
same call for "api/abp/application-configuration" work on app start because that time token is not attached in request header
i check my app setting CorsOrigins are matching with IdentityServerClientCorsOrigins
no space issue both angular and front end on https but with different port. you can verify with logs. one thing is strange in log no protocol attach # respond. (domain:1000)
I check and confirm that this is Authentication issue. by comment these two line and Authorize attribute from class
My application works fine. no issue for cors
app.UseAuthentication();
app.UseJwtTokenMiddleware();

It is not a CORS issue, instead it is because your API (the UseJwtTokenMiddleware part) can't reach your IdentityServer over HTTP(s). I guess you got some DNS/Certificate/Network issue to resolve.

How did you configured proxy in your firefox? Do you have proxy only for http or also for https? If you are proxing also https requests then in recorder settings you need to switch "HTTPS mode" to "Certificate Authority". There will be a button to generate new certificate authority file that you need to import to your browser (Preferences / Privacy & Security / Certificates / View certificates / Import). After that your browser will know that it can trust Gatling proxy server and you should be able to proxy also ssl requests.
I am trying to setup zookeeper on ec2 two instances. as given here and here.
I am trying to run zookeeper which fails with an error:

zoo.cfg as bellow
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper
clientPort=2181
server.1=localhost:2888:3888
server.2=<My ec2 private IPs>:2889:3889
also I have created myId file as on both ec2 instances - /var/lib/zookeeper/myid
I also tried to edit /ect/hosts file but still facing the same issue.
also how I can start both of the zookeeper instances by 1 command?
Note: Server get started successfully if I tried with bin/zkCli.sh start command.
Thanks in advance!
look zk log zookeeper.out，if there have connection limit error, configure the following to zoo.cfg.
# the maximum number of client connections.
# increase this if you need to handle more clients
maxClientCnxns=60
This is temporary error , for mine after some time , It gone away :-
This is my zoo.conf file ::-
Dir=../data
clientPort=2181
tickTime=2000
initLimit=5
This error occurred when I forgot to run% ZOOKEEPER_HOME% \ bin \ zkserver.cmd
By running, the problem has been resolved.
Correct this property on the server.properties
default would be localhost change it to match the zookeeper server starup ip and port
zookeeper.connect=0.0.0.0:2181

Isn't that error message verbose enough?
I am trying to upload some data to my local datastore in appengine.
The command I am using is the next one:
appcfg.py upload_data --config_file="C:\config.yml" --filename="C:\mycsv.csv" --url=http://localhost:8888/remote_api --kind=MyEntity
The problem is that I'm working behind my company proxy and I am getting the next ERROR even trying to connect to the localhost server:
Error Code: 502 Proxy Error. The ISA Server denied the specified Uniform Resource Locator (URL). (12202)
It seems the authentication is ok, but somehow the proxy tries to filter my connection to my own computer.
Some ideas about how can I solve this?
Thanks.
Remove/disable proxy settings of your network then try the above command.
I was facing the similar issue and this issue resolved when i disable my proxy settings.
