description of problems I am having with shiftr.io

This sketch reads three analog values and sends them twice a second to a mqtt broker. Two implementations are provided running on Arduino MKR WiFi 1010, one uses the official ArduinoMqttClient library and the other one uses Joel's 256dpi MQTT library.

This is using the ArduinoMqttClient library. It works great with shiftr desktop, but when using it against a shiftr instance it chokes.

#include <ArduinoMqttClient.h>
#include <WiFiNINA.h>

cool for printing
int i,s=450;void setup(){size(900,900,P3D);}void draw(){translate(s,s);rotate(--i*.1,i%9,i%7,i%4);fill((-7<<i%36)-1);rect(s,0,30,30);}//#p5

simple p5 sketch in a tweet that draw a sphere animation with some perlin noise
float i;void setup(){size(900,900,P3D);}void draw(){translate(450+450*cos(i*.9),600+400*sin(i+=.01)*noise(i));sphere(30/noise(i));}

a tiny processing sketch that generates Mondrianesque compositions (in 287 characters)
int i,j;color clr=#ff0000;void I(int a,int b,int c,int d,int N){if(N==0){fill(clr);clr<<=2;clr%=0xffffff;rect(a,b,c-a,d-b);}else{i=int(random(a,c));j=int(random(b,d));I(a,b,i,j,N-1);I(i,b,c,j,N-1);I(a,j,i,d,N-1);I(i,j,c,d,N-1);}}void draw(){background(#1356A2);I(-1,-1,width,height,2);}

Serial input to Wekinator, supporting both micro:bit and Arduino inputs, made for Deborah's wekinator project.
// (c) 2019 DATA Design, Art and Technology Arnhem
// for and by Deborah Mora
// BASED ON:
// Sends BBC micro:bit to OSC
// By Rebecca Fiebrink: January 2016
// Sends to port 6448 using OSC message /wek/inputs
// Number of features varies according to feature selection in user drop-down (more info on screen)
// @NOTE communication with external devices is expected at 115200
