Hello Chaosmonk
Though I want to thank all who have tried to help me with this problem, I'm
specially addressing you because when reading this topic before sending this
message I discovered that despite the information I provided in my messages
from Thu, 11/10/2018 - 00:39 UTC+1 and from Thu, 11/10/2018 - 06:18 UTC+1
were in response to your very useful request from Wed, 10/10/2018 - 22:45
UTC+1 I directed (by mistake) that information to another user who was also
trying to help me at that time. Sorry for the delay in letting you know these
things just now.
The problem was solved but it took a lot of time and tests that unfortunately
have only left suspicions and not certainties.
I can't say I know what has happened because making some of the suggested
changes (and others) in the starting link did not solve the problem and my
suspicions on a typo have again increased because at the level of the
destination file's name, I found a sort of typo that is not easy to discover
if you use the "Caja File Manager 1.12.7" in the "Browser" mode and "icon
view".
After correcting it the problem has practically dissappeared.
I'm using "practically dissappeared" because the first time I clicked on the
starting link after having corrected the up-mentioned typo, I got a response
that was similar to the one I attached to my post on Thu, 10/11/2018 - 06:18
UTC+1.
But since that last failure which happened several days ago, the troublesome
link has never failed again.
I reiterate: Thanks to all who tried to help!!
