Hi everyone, I am having a hard time filtering data on a TS chart. It doesn't matter which kind of combination or conditions I use all data is removed when the filter is applied.
It seems simple, its a number type of value. I have tried to follow the "Advance Filtering" video tutorial but it does not work, even with the demo samples from thingsboard. Could someone give me a hand with that? Thanks!

@abhinav_singwal_twitter well I also need the answer . I wil share what I did , I used an aggregator stream and then used the sum aggregator function inside it and then also tweaked some other settings and it is working. But the problem in this approach is that you won't get the last 12 hrs every time. What it does is it will try to sum up the values that lie between an interval like 9 am to 8 pm . Then at 8 05 pm the output by the node will be reset to zero . Hope that helps you . 😇

Hi,
I have this SSL/certificate problem with HAProxy and Let's Encrypt, which is a bit challenging.
The description comes right below:

I've installed Thingsboard monolithic architectre with Docker on Ubuntu 20.04.
Now, I wanted to enable https access using HAProxy and Let's Encrypt certificate, as instructed in the tutorial
https://thingsboard.io/docs/user-guide/install/pe/add-haproxy-ubuntu/
Everything goes well until this command: certbot-certonly --domain your_domain --email your_email
that throughs the following error: (I changed my real domain for myservernameanddomain)

    Saving debug log to /var/log/letsencrypt/letsencrypt.log
    Plugins selected: Authenticator standalone, Installer None
    Obtaining a new certificate
    Performing the following challenges:
    http-01 challenge for myservernameanddomain
    Waiting for verification...
    Challenge failed for domain myservernameanddomain
    http-01 challenge for myservernameanddomain
    Cleaning up challenges
    Some challenges have failed.

    IMPORTANT NOTES:
     - The following errors were reported by the server:

       Domain: myservernameanddomain
       Type:   connection
       Detail: Fetching
       http://myservernameanddomain/.well-known/acme-challenge/mbtYDn0iVSCGRaWyAO0KsV0m5yWSGOgMdzr_pPwx9-o:
       Timeout during connect (likely firewall problem)

There is no issue with the firewall. In fact I disabled it to discard any problem related to it.
I've also checked the access to the server and it has a type A DNS record, so its accesible via DNS. ( but it does not have AAAA record, which I believe is for ipv6, and can't tell if it is part of the problem)

I would appreciate any help in solving this issue, as I believe it is important to enhance security.
Thank you !!

Is it OK to deploy thingsboard as a cluster without using the microservice deployment? Running 2+ monolithic nodes for high availability/scaling is preferable for us than having 2+ of each required microservice

Hi All. Does anyone know what directory location would be best to save Js library on Thingsboard Server for use in custom widgets via Widget Resources ? We are using CDN at the moment but its not loading fast enough and thought it would be better to save the library on local TB server. Any advice gratefully welcome.
