@josemvm I do not replicate the issue, it works for me.

I'm adding a WFS layer, using https in #4910

Is your WFS layer quick enough ? It depends on your QGIS Server settings.
Is your layer visible in the map ?

@Gustry

Is your WFS layer quick enough ?

not very very quickly but it visible in the map on qgis desktop (not in lwc) and i can work as well with it

It depends on your QGIS Server settings

what kind of settings in qgis server

i will test #4910 and if you want to test my layer I can provide the url as it is open data

[Gustry]

There is nothing to test in #4910. It was just to add test data.

We got sometimes the issue about the SSL handshake being written in a SQLite from QGIS, where QGIS server didn't get write permissions on this file.
You should check QGIS Server logs if there is kind of data.
What is the error in LWC about this blank tiles ? or logs in QGIS server during this request ?

We got sometimes the issue about the SSL handshake being written in a SQLite from QGIS, where QGIS server didn't get write permissions on this file.

22:03:56 WARNING WFS[1425]: Cannot create temporary SpatiaLite cache.: Cannot copy file to //.local/share/QGIS/QGIS3/profiles/default/cache/wfsprovider/pid_1425/cache_4.sqlite:

[josemvm]

the wfs layer is visible only at 1:250000, if i zoom to a major scale the layer disappears!
also the attribute table doesn't appear filled in, only the field names are visible

[rldhont]

@josemvm I think your QGIS Server needs the environmental variable to define the home directory

[josemvm]

@rldhont thanks for your answer

now i' ve the environmental variable

FcgidInitialEnv QGIS_OPTIONS_PATH "/home/qgis/.local/share/QGIS/QGIS3/profiles/default"

the structure folders:

/home/qgis/.local/share/QGIS/QGIS3/profiles/default

and the error remains:

WARNING WFS[4667]: Cannot create temporary SpatiaLite cache.: Cannot copy file to //.local/share/QGIS/QGIS3/profiles/default/cache/wfsprovider/pid_4667/cache_2.sqlite:

[Gustry]

Cannot copy file to //.local/share/

I doubt that your process can write to this directory...

[josemvm]

I doubt that your process can write to this directory...

@Gustry i don't know why!
owner: root, group: www-data
permissions: all (777)

[Gustry]

On which directory did you check this owner and group ? Look at the path in my message.

[josemvm]

On which directory did you check this owner and group ?

from qgis/.local/share/QGIS/QGIS3/profiles/default in /home/ to the end

[josemvm]

@Gustry please where do you point me with

Look at the path in my message

(?)

[Gustry]

Cannot copy file to //.local/share/QGIS/QGIS3

It's trying to write in //.local.

[josemvm]

i think that one slash (/) = double (//) slash...
this mean that the process needs to write at root file system /.local ?

[josemvm]

ok! so the qgis server ignores the environmental variable QGIS_OPTIONS_PATH ... (?)
thank you so much @Gustry :-)

[Gustry]

ok! so the qgis server ignores the environmental variable QGIS_OPTIONS_PATH ... (?)

No, it works, but then it's the value of QGIS_CUSTOM_CONFIG_PATH which overrides the other one.

Try to set both with the same value.

thank you so much @Gustry :-)

That's why I pointing you to read your own logs ;-)

[Gustry]

There is also QGIS_AUTH_DB_DIR_PATH, and HOME.
