I have migrated to another country and this has caused my Blynk projects controlling various Photons to not connect. Has anyone had a similar issue?
Do to a DNS problem i now use a static ip to connect to Blynk server. How do I do this also in Particle Sketch?
Have a look at setting a static ip in the documents in the wifi section.
I have read through the Particle and Blynk docs. Still having trouble connecting the Particle Photon to the cloud.
This has all started since I moved to another country. I had to use a static ip to connect blynk app to server.
The only way Photon connects to cloud is in safe mode.
Trying to connect to blynk server in my opinion is pointless since the Photon cant even connect to Particle Cloud.
Don’t know where to start from.

Managed to connect Particle Photons with Blynk Cloud with the following.
char auth[] = "××××××××××××××××××××";
char server[] = "45.55.96.146:8443";
Blynk.begin(auth, server);
Mark as solved.
