> Key: GUACAMOLE-1235
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1235
> Project: Guacamole
> Issue Type: Bug
> Components: guacamole
> Affects Versions: 1.2.0
> Environment: Clients and server used during tests run Linux.
> Client affected:
> Client 1: Debian 9
> Client 2: Ubuntu 20.04
> Server: CentOS 7
> Guacamole: 1.2.0
> Reporter: Pietro G
> Priority: Major
> Attachments: guacamole-client-log.txt, guacamole-server-log.txt,

>
> 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
