[jira] [Updated] (GUACAMOLE-1235) Client timeout anomaly
[ https://issues.apache.org/jira/browse/GUACAMOLE-1235?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pietro G updated GUACAMOLE-1235:
--------------------------------
Description:
I have been testing guacamole connection sharing through share links but unfortunately something strange happens.
From a client connected to the shared connection using the share link and through a fast 4G connection I get this error message quite often; let's say every minute:
!image-2020-12-10-11-51-06-284.png!
if I click on the "Reconnect" button immediately after its appearance, connection is reestablished and everything runs fine for the following minute, then the error starts appearing again.
The situation is quite strange as the connection is fast and there are no issues or slowdowns while surfing the Internet or using other network applications.
I have tested with another computer using a WiFi connection and another 4G and the issue sometimes occurs but not that often (one hour+ with no issues)
Then I tested with a third computer using a 3G/H+ connection and the issue occurs with the same frequency (1 or 2 minutes).
*In the attachment logs for: guacamole-client, guacamole-server, reverse proxy*
Here is a small schematic about the environment:
Client Browser → Internet → Reverse Proxy → Tomcat (serving GuacamoleClient) → guacd → RDP server
Between the client browser and the reverse proxy there are no components that could buffer data (e.g. forward proxies, antivirus software, ...).
Could you give me some suggestions?
More details about the environment in the Environment section
Thank you very much in advance
