[SOLVED] Error on Certificate generation

Solved
1

I have this kind of error, what should i do?
Im newbie here, just using blynk for my project

2

Hello. Did you add port forwarding as stated in docs?

You need to start server on port 80 (requires root or admin rights) or make port forwarding to default Blynk HTTP port - 8080.

3

I already start the server at port 80, i think the problem is at server. host which i dont have my own host or domain

4

So what exactly do you expect from certificate generator in that case?

5

any alternatives sir? or is it ok if i disable auto generation?

6

That’s ok. Server has embedded certs.

7

Ok sir, so how can i enable the email to notify me or my client?

Read the docs regarding this.

10

i already did that but the problem is i dont have any host or domain to be input at the server.host

11

Yes it is.

12

ok so i will just ignore the WARN? is it right?

13

Yes it is and if you don’t receive emails the problem is elsewhere within your set up e.g. not using gmail, not configuring gmail correctly etc

14

thanks sir, i already set up my gmail at mail.properties

Having the same problem. Looks like the domain lookup fails. My guess is it’s because I’m usin a dynamic domain
