I have one question, regarding the local legacy blynk server:
I am running blynk local server and everything are great. Today I tried to export (from blynk legacy Android app) my super chart values. I selected Export to CSV and little time later I got an email from my local blynk server with subject: “History graph data for project PZEM-004 esp8266”, that’s my project, with the links to download the (4) the corresponding XXX.csv.gz files. The problem come up here, when I click to any of these four links I get to my browser:
This site can’t be reached xxx.net unexpectedly closed the connection
Obviously I have something wrong in my configuration, I running Ubuntu 22.04 server with nginx web server. Do you have any idea what to check or what to adjust for proper working of the links?
In addition, When I ssh my server, I found the 4 exported files at /tmp/blynk (I don’t know why they exported there though) …
