MetaSearch leverages OWSLib for CSW request/response handling which results in also using OWSLib's HTTP request/response handling.

Using QGIS' @QgsNetworkAccessManager@ provides numerous benefits (HTTP auth, proxy, etc.) in accessing the network in a uniform way via QGIS.

Update MetaSearch to implement @QgsNetworkAccessManager@. This will likely require changes to OWSLib as an initial step to abstract HTTP handling.

What is the status of this ticket @tomkralidis ?
Did you switch to use the native QGIS network access manager ?

[tomkralidis]

@Gustry no update, but we should keep open to be able to move into native QGIS HTTP/HTTPS handling.

to be able to move into native QGIS HTTP/HTTPS handling

Would be great, given this is a core plugin.

Use behind http proxy seems to be broken for some reason -> #53159 (comment)
