In WPML > Support I can see the issue description on the screenshot. Here the translation:
WPML plugin cannot connect to wpml.org
WPML needs to connect to your server to check for new releases and security updates. Something present in the network or security configuration is preventing this. Please authorise outgoing communication with wpml.org to remove this warning.
Need help?
See the communication error details and report it to WPML support.
Issues like this can sometimes take place for multiple reasons (sometimes they are even server-related).
I recommend that you first create a full website backup and then remove the plugins completely (deactivate and delete) > then manually download the latest versions from here (https://wpml.org/account/downloads/ - select "Download WPML manually" button) > download the 3 plugins > then install and activate the plugin. You can go to Plugins > Add new > Upload > and upload each zip one by one, where you install and activate each of the three plugins' latest version.
This way (by going with a manual update), we might get over this error.
