Same here, it’s not working.
I’m paying Google 36,000 yen/month for their enterprise Ultra plan, so I want this bug fixed immediately.

today, same issue on all models, shaame the service is getting worse after each update… even downgrading didn’t help… please fix
can you describe how you nuked? i tried nuking everything as well, redownloaded and reinstalled, but it still doesn’t work
ugh sorry I didn’t save the original script. but if you nuke + redownload and open Antigravity and see old convos, then not everything was actually wiped. I did it twice, first time did not fix
This one is outside the standard mac app sweep:
~/.gemini/antigravity
Gemini agent thinks bad server connect will show up here if you have it:
~/Library/Application Support/Antigravity/logs/latest/ls-main.log.
Google silent to this shown either they don’t know how to fix this issue or it’s actually by design, smh.
our servers are experiencing high traffic right now
Ultra Subscribers….

still no solution? actually i really confuse on my friend computer things go normal, on my secondary laptop normal too, but on my working computer the error happen again and again
i already do uninstall and install the error still exist.. do antigravity ban our several device? really confuse actually
Ve aniden, muhtemelen 50 deneme sonrasında, bana token limitine ulaştığımı söylüyor. Bu nasıl mümkün olabilir? Bu denemeler neden kullanım limitime dahil ediliyor? Lütfen bu hatayı düzeltin - böyle bir şey olmamalı! Ultra Abone
this doesn’t seem to work for me unfortunately 
¿El error de que los servidores tienen mucho tráfico se arreglará en algún momento? Nunca uso mi cuenta plus para nada de esto, pero me parece una vergüenza que lo quiera usar después de semanas en antigravity y no funcione. A saber el destrozo que se le está haciendo los profesionales que pagan para poder usar la plataforma. Desde luego es para pensarse cambiar a otras opciones.
I’m constantly encountering this issue too, here’s the debug info:

I feel that subscribing to any service with antigravity is completly useless as long as this is happening.. it just burns tokens for nothing
on ultra plan, constantly getting this error hugely and very frequently these days
Can’t get any work done, this keeps occurring. To make things worse, there’s been 1000+ of credits wasted on this error just today and the day haven’t even started
This is absolutely unusable and a huge waste of credits - Have been happening for weeks and only getting worse!
I am trying to use the Opus model and it keeps throwing the “high traffic” error - with nothing useful getting done, on pressing “Retry” it just auto-prompts “continue”, but after 2-3 such attempts it seems to almost completely forget what it’s supposed to be doing!
Nothing got done and I’ve lost 40% of my current 5-hour-window credit allowance after just a few such “continues”. Probably wasted thousands of credits on this earlier without noticing (I am on Ultra plan).
This is the worst experience with any product I’ve had in my life, especially for such a premium price. If I am not granted all my wasted credits back I will not be renewing this subscription.
Extremely disappointing experience.

Im on the same boat. AG is updated already to the latest. Whats the point of all these complaints if we dont get a single response from Google Team?
Firstly, slow… then occur high traffic all the day… Finally, lost the conversation after many Retry clicked…
Hello everyone!
