Unable to send out gmails

[L58]

I have set up my RBR50 mesh wifi with 1 satellite. When using the Orbi wifi network all my gmail outgoing messages from my iphone (model XS) do not go through. If I change to another Wifi network everything works. Instead Emails going out from the gmail account from the iMac using Orbi wifi network seems to have no problems.

I have tried to reset account on the iPhone, change the smtp.gmail.com ...but nothing  worked. 

Help will be appreciate as I do not know what to do.

Thanks

What Firmware version is currently loaded?
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Is Armor, Circle, or IPv6 enabled on the RBR? 

[L58]

The firmware for the router and the satellite are : V2.5.1.16

The internet provider is Post Luxemboug ( the state telephone Co)

The Modem model is the Fritz Box 7490 - this is the standard modem that come with the installation of the internet

Armor, Circle or IPv6 is not enable on the RBR

Thanks for any help

Need to check your ISP modem as this modem has a built in router already. Is this modem bridged or working router mode? 

This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

Check with your ISP if they can help you bridge the modem if possible.
