I’m trying to backup my QNAP to Backblaze B2 using BB’s guide ( https://www.backblaze.com/docs/cloud-storage-integrate-qnap-hybrid-backup-sync-3-with-backblaze-b2 ), but keep getting the following error when I try to create the job: Error Cannot upload to the cloud service. Network Error. I don’t …

@SteveKo – thanks for the advice via PM. If this issue is potentially due to SSL inspection or Proxy interference, do you know what ports would need to be opened? I’m just running an Asus router (with Merlin WRT) with largely default settings (aside from setting cloudflare 1.1.1.1 as DNS), but I c…

Hi @SteveKo – just checking in–any news from your colleagues? Thanks!

You would not open any ports on your router. Outbound communications don’t need open ports and any communication back from Backblaze is handled because the initiation was from your end. Have you opened a ticket with Backblaze? It might not be QNAP related…

Regarding the Backblaze B2 connection issue, here are our troubleshooting suggestions: Communication Ports: The B2 service uses standard HTTPS (Port 443) for communication; typically, no additional special ports need to be opened. Network Architecture: As we are currently unclear about your ne…

@SteveKo @NA9D Thanks for the responses. I’ll open a ticket with BB. @SteveKo , some answers to your questions: Great to hear. FYI…using a port scanner (like this ), all server ports (21, 22, 23, 25, 53, 80, 110, 137, 138, 139, 143, 443, 445, 548, 587, 993, 995, 1433, 1701, 1723, 3306, 5432, 800…

OK. You probably don’t have your business router put into Bridge Mode. It is probably in router mode. You can see this by going to: What Is My IP Address? IP Address Tools and More IP address lookup, location, proxy detection, email tracing, IP hiding tips, blacklist check, speed te…

The router is in bridge mode–I’ve got a static IP from Comcast which is what my router reports (i.e. it’s not a private IP). Is putting the NAS on the DMZ any more dangerous than connecting it directly to the Comcast modem for troubleshooting purposes as @SteveKo has recommended?

Is that static IP assigned to the Comcast device or your Asus router?

@Becker2020 I just upgraded, but alas, it did not rectify this issue. @SteveKo I briefly set my router to put the QNAP on DMZ, but this also did not change the outcome. As another test, I attempted to create a backup job to Dropbox, and I was at least able to create the job–which is further than I…
