  Ok, we have a problem.
  
  @Manuel @ItamarWMDE @WMDE-leszek @Lydia_Pintscher
  
  After having rebuilt only two of the Wikidata Analytics images on 
`wikidata-analytics` in the `wmde-dashboards` CloudVPS project - in an attempt 
to actually cure something else, namely the Wiktionary Cognate Dashboard - the 
whole system became irresponsive following the same pattern that @ItamarWMDE 
and I have already faced (and failed to understand) in 2022 during our work on 
the `wmdeanalytics` CloudVPS projects. It is simple:
  
  - the containers time-out under ShinyProxy <https://www.shinyproxy.io/faq/>.
  
  Currently, **not only the Wiktionary Cognate Dashboard, but the whole 
Wikidata Analytics suite is unavailable.**
  
  The problem in CloudVPS has nothing to do with any known ShinyProxy related 
problematics:
  
  - **I can run the Docker containers manually and they respond without any 
errors**
  
  - **I can also replicate the whole Wikidata Analytics suite**, with exactly 
the same architecture (for R specialists: ShinyProxy + containers from images 
built under the Golem framework) as we have on our CloudVPS virtual machines, 
**on a separate, test server, and it delivers there without any hiccups**;
  
  - **ergo:** this has something do with the setup of the CloudVPS machines, be 
it some Puppet run that changed something, or something else that a DevOps 
engineer might be able to help around - but that I can certainly not help 
around.
  
  It would be a pity to lose the functionality of a five year long development 
of Wikidata Analytics and Wiktionary Cognate (2017 - 2022) for reasons related 
to system engineering. And please do not tell me that it is something peculiar, 
R related thing - R is the 13th most popular programming language on the Tiobe 
index in 2022, it has native support in standard MLOps solutions like AWS 
SageMaker, etc. So it's not R, and it is not ShinyProxy, nor it is anything 
else R related; it is something related to the underlying setup of the CloudVPS 
machines.
  
  Let me know when you find someone who can make a deep dive into this.
