[Fiware-lab-help] CEP instance problem

[Marios Protogiros]

Dear Javier,
this was our first issue regarding the initial loading of CEP.
We have tried the last image of CEP on a new instance with Docker with all
possible browsers.
The UI Administration although is still slow, we have overcome it by having
a continuous open session on a VPS so regarding the question you could close
it as ticket as it escalated.

We had,and still have, a number of other issues since that, and we sent
another email  from 24th of September on which we still have *no answer*
and all the problems that come with that in our development.

Below is the email from 24th of September, to let you aware of.

Regards,
Marios Protogiros
